It's no-go here:

    GEN      ../../etc/charsets/ALTERNATIVNYJ.map
  make: *** No rule to make target `/usr/share/i18n/charmaps/GB18030.gz', needed by `../../etc/charsets/GB180302.map'.  Stop.

If I remove GB180304.map from the value of LOCAL, it goes on, and then
fails again:

    GEN      ../../lisp/international/cp51932.el
  make: *** No rule to make target `/usr/share/i18n/charmaps/EUC-JP-MS.gz', needed by `../../lisp/international/eucjp-ms.el'.  Stop.

at which point I stopped trying.

I assume the same failure will happen on any non-glibc Posix host as
well.

Maybe we should simply import that glibc directory, and use our own
copy?  It makes little sense to me to be able to generate only a part
of the maps, but not the others.
