[Bug-gnulib] gl_USE_SYSTEM_EXTENSIONS fix for AIX, MINIX

[Paul Eggert]

A user bug report about AIX caused me to notice that gl_USE_SYSTEM_EXTENSIONS
doesn't enable AIX's extensions as desired.  I guess MINIX has the same
problem (does anybody still use MINIX)?  I installed this patch.

        * extensions.m4 (gl_USE_SYSTEM_EXTENSIONS): Require AC_AIX
        and AC_MINIX, too, so that their extensions are available.
