c33b199456guix: Bump glibc and linux-headers (Carl Dong)65363a1bd8guix: Rebase on 95aca2991b (1.2.0-12.dffc918) (Carl Dong) Pull request description: On bumping the time-machine: ``` A few changes which are useful for us: 1. 'gnu: cross-gcc-arguments: Enable 128 bit long double for POWER9.' is now merged into master. 2. gnutls is bumped to 3.6.15 and the temporal test failure in status-request-revoked is fixed. Note that this does not fix the case where one has installed Guix v1.2.0 and is running a substitute-less bootstrap build, since the `guix time-machine` command itself has a dependency on gnutls v3.6.12 (the one with the broken test) and will thus try to build it before attempting to jump forwards in time. This does however, mean that those who build a version of Guix that also contains this fix will not go backwards in time to build the broken gnutls v3.6.12. ``` On bumping the rest: ``` Bump glibc and linux-headers to match those of our Gitian counterparts. We also require a glibc >= 2.28 for the test-symbol-check scripts to work properly. The default BASE-GCC-FOR-LIBC also has to be bumped since glibc 2.31 requires a gcc >= 6.2 ``` This is a prerequisite for #20980 ACKs for top commit: fanquake: ACKc33b199456- I think going ahead with this now and to sycn back up to gitian is fine. It will also unblock #20980. Potential code signing related issues can be sorted out in #21239 and later PRs.

# GUIX_BUILD_OPTIONS is an environment variable recognized by guix commands that
|
|
# can perform builds. This seems like what we want instead of
|
|
# ADDITIONAL_GUIX_COMMON_FLAGS, but the value of GUIX_BUILD_OPTIONS is actually
|
|
# _appended_ to normal command-line options. Meaning that they will take
|
|
# precedence over the command-specific ADDITIONAL_GUIX_<CMD>_FLAGS.
|
|
#
|
|
# This seems like a poor user experience. Thus we check for GUIX_BUILD_OPTIONS's
|
|
# existence here and direct users of this script to use our (more flexible)
|
|
# custom environment variables.

Unfortunately this script is incompatible with GUIX_BUILD_OPTIONS, please unset
|
|
GUIX_BUILD_OPTIONS and use ADDITIONAL_GUIX_COMMON_FLAGS to set build options
|
|
across guix commands or ADDITIONAL_GUIX_<CMD>_FLAGS to set build options for a
|
|
specific guix command.
