Comment:
So the `cross-powerpc-linux-gnu` problem seems to be a parallelism issue. I have `XBPS_MAKEJOBS=120` in `etc/conf`. In another try I could now build the pkg with both, my own pkgs and the official ones in a `binary-bootstrap i686`.

However the failure to build `glibc` happens here also with the official binaries, i.e.:
```
./xbps-src zap
./xbps-src binary-bootstrap i686
./xbps-src -a ppcle pkg glibc
```
fails for me just as with my home grown `i686` pkgs. My `etc/conf` is:
```
XBPS_MAKEJOBS=120
XBPS_CCACHE=yes
XBPS_DEBUG_PKGS=yes
XBPS_ALLOW_RESTRICTED=yes
```
Kernel is `linux-5.11.2_2` and I'm going to try on the `5.10` series now.
