[PATCH 0/1] improve build reproducibility

[Juro Bystricky <juro.bystricky@intel.com>]

There is a subtle non-determinism when building glibc.
Basically, under the same conditions (same build host, toolchain, etc.) we occasionally
ended up with slightly different binaries. This was eventually tracked down to the fact
that sometimes the libraries were built using the checked-in intl/plural.c and some other
times using a different version of intl/plural.c generated by Bison from intl/plural.y.
It seems that the generation of intl/plural.c is not quite deteministic, most likely due
to the fact that GIT does not preserve file modification time.

This patch proposes to unconditionally generate plural.c from plural.y

More on the subject (including a diffoscope output that demonstrates the differences) can

There is also bug filed in glibc Bugzilla:
