glibc-2.33 fails to build on POWER9

glibc-2.33 fails to build on POWER9

[Tobias Platen]

I tried to build glibc-2.33 on my Talos II (no cross compile here),
it fails because the compiler is likely outdated.

checking if the target machine is at least POWER8... yes
checking if the compiler supports -mno-gnu-attribute... yes
checking if gcc compiles signbit with 128-bit floating point type...
yes
checking if gcc compiles with -mabi=ieeelongdouble and -mlong-double-
128... no
checking for objcopy... objcopy
checking version of objcopy... 2.37, ok
configure: error: ***  The compiler must support -mabi=ieeelongdouble
and -mlongdouble simultaneously.

guix --version shows

Can you try with a more recent version of Guix? Is this for building
glibc@2.33 or as part of the packages in commencement.scm?

This commit is 5 months old. Have you tried a recent one? Though I don't
think the age of the commit is at issue here since I don't see the
problem on the guixp9 POWER9 KVM guest — neither with that commit nor
with one from yesterday:

The last glibc build on the master branch also went well in the CI
(which also uses guixp9 so not really a different data point):

Can you share more details that might be relevant about your environment
and how you are building the package?
