glibc: Do not use parallel make for building locales (#1652228)
I would like to see a quick review for this.
I think have to do this, which is unfortunate. It increases build time
by about ten minutes on x86-64 (with lots of CPU cores).
Proposed patch:
diff --git a/glibc.spec b/glibc.spec
index 73ecd93..54c96b2 100644
--- a/glibc.spec
+++ b/glibc.spec
@@ -908,7 +908,9 @@ make -j1 install_root=%{glibc_sysroot} install -C build-%{target}
# locales.

+make install_root=%{glibc_sysroot} \

popd
%endif
I think this could also explain the x86_64/i686 multilib differences for
the locale archive that we saw downstream occasionally.
Thanks,
Florian
