Changing the first build to a UTF-8 locale?

[Adrian Bunk]

Hi,

there are currently several reproducible-only build failures due to
export LANG="C" in the first build.

Would it be OK to set LANG to C.UTF-8 or en_US.UTF-8 in the first build 
instead?

Building under non-UTF-8 locales feels pretty pointless at this time, 
and the build failures this causes in reproducible are annoying.

The second build is already using a UTF-8 locale.

The Debian buildds are already using C.UTF-8 for years.

Thanks
Adrian
