Closed issue by meator on void-packages repository

https://github.com/void-linux/void-packages/issues/49207

Description:
### Is this a new report?

Yes

### System Info

Void 6.6.18_1 x86_64 GenuineIntel uptodate hold rrrdDFFFFFFFFFFFFFFFFFFFFFFFFFFFF

### Package(s) Affected

libstdc++-13.2.0_2 libstdc++-devel-13.2.0_2 libstdc++-dbg-13.2.0_2

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

_No response_

### Expected behaviour

Everything being all right.

### Actual behaviour

I have the following program:

```c++
#include <string>

int main() {
    std::string{std::string{}};
}
```

When I compile it with

```
g++ -ggdb main.cpp
```

, debug it with `gdb` and try to step in the fourth line, I get
```
std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >::basic_string (this=0x7fffffffe590)
    at ./build/x86_64-unknown-linux-gnu/libstdc++-v3/include/bits/basic_string.h:512
warning: 512	./build/x86_64-unknown-linux-gnu/libstdc++-v3/include/bits/basic_string.h: No such file or directory
```

`gdb` is trying to look into `./build/x86_64-unknown-linux-gnu/libstdc++-v3/include/bits/basic_string.h`, but it should be looking in `/usr/include/c++/13.2/bits/basic_string.h`.

This looks like `./build/x86_64-unknown-linux-gnu/libstdc++-v3/include/bits/basic_string.h` was the path in the build step of `libstdc++` (which is a subpackage of `gcc`) in the masterdir. This path doesn't match the path in a real installed system, which rightfully confuses gdb.

I have `libstdc++-13.2.0_2` `libstdc++-devel-13.2.0_2` and `libstdc++-dbg-13.2.0_2` installed, so I shouldn't be lacking debugging symbols.

### Steps to reproduce

I have first created this recording with slightly different code and it was intended for `#voidlinux`, but it is still relevant and useful: https://asciinema.org/a/646146
