[PATCH:luit 0/3] configure.ac cleanups & bug fix

[Alan Coopersmith]

Trying to fix https://bugs.freedesktop.org/show_bug.cgi?id=47792 as
well as cleanup some other messes in the configure script.

Works for me on Solaris, but could use confirmation on Linux, since
that's where the bug is reported and the changes most affect.

Alan Coopersmith (3):
  config: Add missing AC_CONFIG_SRCDIR
  Replace hardcoded _XOPEN_SOURCE=500 with AC_USE_SYSTEM_EXTENSIONS
  Merge overlapping AC_CHECK_HEADERS & AC_CHECK_FUNCS calls into one
    set
