Description of problem:
After gcc was updated to version 10.0.1-0.13 the build of root started failing in koschei for aarch64 with a missing symbol during linking:
Version-Release number of selected component (if applicable):
I triggered a second attempt in koschei and it failed the same way.
Steps to Reproduce:
1. Build root in rawhide
Build fails with missing symbol
/usr/bin/ld: /usr/include/c++/10/ext/atomicity.h:50: undefined reference to `__aarch64_ldadd4_acq_rel'
On aarch64 -moutline-atomics has been turned on by default, and those symbols are solely in libgcc.a, not in libgcc_s.so.*.
So, libgcc_s.so linker script is needed instead of libgcc_s.so symlink like on some other arches, gcc-10.0.1-0.14.fc33 with a fix is building in koji.
Should be hopefully fixed in gcc-10.0.1-0.14.fc33.
This is also currently a problem on Fedora 32: https://koji.fedoraproject.org/koji/taskinfo?taskID=44074576 and there do not appear to be any new builds.
Yes, because the F32 build wasn't intended to be pushed, I built it in F32 too just because some people wanted it.
Now also affects Fedora 32 with gcc-10.0.1-0.13.fc32, see e.g.:
Hovever, rawhide is no longer affected with gcc-10.0.1-0.14.fc33. see e.g.
Please, can we get the broken build untagged from Fedora 32? This is blocking other packages.
