package/localedef: compile against glibc-2.29

In glibc 2.27 the following change occurred:
"Statically compiled applications attempting to load locales compiled
for the GNU C Library version 2.27 will fail and fall back to the
builtin C/POSIX locale."

This impacts us since upstream buildroot uses a localdef built against
an older eglibc release, as reported at [0].

This is a combination of my patch to move to glibc and Peter Seiderer's
patch to avoid building all of glibc just for localedef.

-This header has been removed in glibc 2.26:

-https://abi-laboratory.pro/tracker/changelog/glibc/2.26/log.html

------------------------- >8 ------------------------
-* The nonstandard header <xlocale.h> has been removed.  Most programs should
-  use <locale.h> instead.  If you have a specific need for the definition of
-  locale_t with no other declarations, please contact
-  libc-alpha@sourceware.org and explain.
