Hi!

While working on the “reproducible builds” effort [1], we have noticed
that newlib could not be built reproducibly.

In particular, the order in which object files get added to archives is
not deterministic. I think the problem is that the locale affects how
the shell sorts filenames.

I've attached two patches. The first modifies Makefile.am files to use
LC_ALL=C when adding members to archives, and as such is suitable for
sending upstream. The second is the equivalent change for Makefile.in,
and us such is suitable for applying to the Debian package (since it
does not invoke automake).

Regards,

Daf
