This cleans up various bits of nastiness in this recipe:
* Drop unneeded m4 macros
* Update to a recent version of gettext (needs addition of Makevars file)
* Drop split do_compile and SUBDIRS hacks, just patch out the docs
* Remove some of the configure.in hacks since they seem unneeded now
and break gettext (the AC_OUTPUT change).
* Wipe out acinclude.m4 since it has corrisive contents
