On bumping the time-machine:
0A few changes which are useful for us:
1
21. 'gnu: cross-gcc-arguments: Enable 128 bit long double for POWER9.' is
3 now merged into master.
42. gnutls is bumped to 3.6.15 and the temporal test failure in
5 status-request-revoked is fixed. Note that this does not fix the case
6 where one has installed Guix v1.2.0 and is running a substitute-less
7 bootstrap build, since the `guix time-machine` command itself has a
8 dependency on gnutls v3.6.12 (the one with the broken test) and will
9 thus try to build it before attempting to jump forwards in time. This
10 does however, mean that those who build a version of Guix that also
11 contains this fix will not go backwards in time to build the broken
12 gnutls v3.6.12.
On bumping the rest:
0Bump glibc and linux-headers to match those of our Gitian counterparts.
1
2We also require a glibc >= 2.28 for the test-symbol-check scripts to
3work properly.
4
5The default BASE-GCC-FOR-LIBC also has to be bumped since glibc 2.31
6requires a gcc >= 6.2
This is a prerequisite for #20980
