New issue by ackalker on void-packages repository

https://github.com/void-linux/void-packages/issues/12760
Description: ### System

* xuname:  
  Void 5.1.15_1 x86_64 GenuineIntel uptodate rrrrmdFFFFFFFFF
* package:  
  mesa-nouveau-dri-dbg-19.1.1_1

### Expected behavior

`gdb` should load debug symbols for the right file, i.e. `/usr/lib/debug/vdpau/libvdpau_nouveau.so.1` should match `/usr/lib/vdpau/libvdpau_nouveau.so.1`, etc., backtrace should contain symbols for all loaded libraries, etc.

### Actual behavior

`gdb` gives debug information mismatch warning, backtrace is missing details

### Steps to reproduce the behavior

(trying to debug void-linux/void-packages#12717)

* On a system using `nouveau` X graphics driver and `gdb` installed, run the following in a terminal:
```sh
# xbps-install vdpauinfo{,-dbg} glibc-dbg mesa-nouveau-dri-dbg
```
* Run `vdpauinfo` under GDB

Results on my system:
```sh
$ gdb -q vdpauinfo 
Reading symbols from vdpauinfo...
Reading symbols from /usr/lib/debug//usr/bin/vdpauinfo...
(gdb) set pagination off 
(gdb) run

Running `objdump -g` on the debug information file confirms the incorrect link:

  CRC value: 0x69940ea

```

My guess is that something went wrong during build or packaging. I haven't looked into it, so I don't know if the problem is with the recipe or with `xbps-src` itself.

Comment:
The problem appears to be with how the build system installs 'megadrivers', i.e. a bunch of filenames all get symlinked to the same master file.
For this issue, on my system, this output from `xbps-src install` step seems relevant (full `xbps-src` install log [here](https://gist.github.com/ackalker/8377b789b50ee6e3b17ccb642e040dd1)):
```
Running custom install script '/usr/bin/python3 /builddir/mesa-19.1.1/bin/install_megadrivers.py /builddir/mesa-19.1.1/build/src/gallium/targets/vdpau/libvdpau_gallium.so.1.0.0 lib/vdpau libvdpau_r300.so.1.0.0 libvdpau_r600.so.1.0.0 libvdpau_radeonsi.so.1.0.0 libvdpau_nouveau.so.1.0.0'
```
This results in a bunch of symlinks, including `libvdpau_nouveau.so.1.0.0`, all eventually pointing to `libvdpau_gallium.so.1.0.0`.

Although there's still a warning, at least the symbol names look somewhat reasonable.

Comment:
The problem appears to be with how the build system installs 'megadrivers', i.e. a bunch of filenames all get symlinked to the same master file by `${wrksrc}/bin/install_megadrivers.py`.

For this issue, on my system, this output from `xbps-src install` step seems relevant (full `xbps-src` install log [here](https://gist.github.com/ackalker/8377b789b50ee6e3b17ccb642e040dd1)):
```
Running custom install script '/usr/bin/python3 /builddir/mesa-19.1.1/bin/install_megadrivers.py /builddir/mesa-19.1.1/build/src/gallium/targets/vdpau/libvdpau_gallium.so.1.0.0 lib/vdpau libvdpau_r300.so.1.0.0 libvdpau_r600.so.1.0.0 libvdpau_radeonsi.so.1.0.0 libvdpau_nouveau.so.1.0.0'
```
This results in a bunch of symlinks, including `libvdpau_nouveau.so`, all eventually pointing to `libvdpau_gallium.so.1.0.0`. It appears that `xbps-src`'s `common/hooks/post-install/06-strip-and-debug-pkgs.sh` doesn't handle these correctly.

Comment:
@ackalker you can test my branch if you like and see if it updates successfully and solves the issue:

1. checkout branch and build libGL
2. `xi -u`
3. additionally install `mesa-vdpau` with `xi` because it is now an optional subpackage, and also install the debug symbols

To revert to the initial state in case something goes wrong:

1. `xbps-remove -F mesa-classic-dri mesa-gallium-dri mesa-vdpau`
2. `xbps-install -f <updated-pkgs>` where `<updated-pkgs>` are the packages updated in previous step 2) and can be obtained by something like `xilog | grep 19.2.2_2`

Closed issue by ackalker on void-packages repository

https://github.com/void-linux/void-packages/issues/12760

Description:
### System

* xuname:  
  Void 5.1.15_1 x86_64 GenuineIntel uptodate rrrrmdFFFFFFFFF
* package:  
  mesa-nouveau-dri-dbg-19.1.1_1

### Expected behavior

`gdb` should load debug symbols for the right file, i.e. `/usr/lib/debug/vdpau/libvdpau_nouveau.so.1` should match `/usr/lib/vdpau/libvdpau_nouveau.so.1`, etc., backtrace should contain symbols for all loaded libraries, etc.

### Actual behavior

`gdb` gives debug information mismatch warning, backtrace is missing details

### Steps to reproduce the behavior

(trying to debug void-linux/void-packages#12717)

* On a system using `nouveau` X graphics driver and `gdb` installed, run the following in a terminal:
```sh
# xbps-install vdpauinfo{,-dbg} glibc-dbg mesa-nouveau-dri-dbg
```
* Run `vdpauinfo` under GDB

Results on my system:
```sh
$ gdb -q vdpauinfo 
Reading symbols from vdpauinfo...
Reading symbols from /usr/lib/debug//usr/bin/vdpauinfo...
(gdb) set pagination off 
(gdb) run
Starting program: /usr/bin/vdpauinfo

Running `objdump -g` on the debug information file confirms the incorrect link:
```sh

  CRC value: 0x69940ea

```

My guess is that something went wrong during build or packaging. I haven't looked into it, so I don't know if the problem is with the recipe or with `xbps-src` itself.
