glibc: ftbfs for ppcle

[pullmoll]

Currently glibc cannot be built for ppcle. When trying to link libc.so the error is:

[q66]

just tried cross-compiling glibc for ppcle, can't reproduce the problem

[pullmoll]

Then something is borked in my local builds. Now trying to build with a binary-bootstrap from the official repo.

[pullmoll]

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.

[pullmoll]

D'OH! Booted into linux5.10-5.10.19_1 and I could build glibc using the official repo while it still fails using my own repo. I'm going to compare build logs now to track down the difference.

Another try w/ official repo gives me this:
log-official.txt

FWIW: The logs cannot really be compared. Despite building with XBPS_MAKEJOBS=1 the outputs differ very much in the order of files being built, time stamps created, etc.
I'll try to rebuild the {host,}makedepends pkgs.

Something to remember if we hit issues with glibc builds, but we won't be able to investigate further :/
