[PATCH] gettext: disable install, docs targets, libasprintf, threads

["Arsen Arsenović" <arsen@aarsen.me>]

This fixes issues reported by David Edelsohn <dje.gcc@gmail.com>, and by
Eric Gallager <egallager@gcc.gnu.org>.

ChangeLog:

	* Makefile.def (gettext): Disable (via missing)
	{install-,}{pdf,html,info,dvi} and TAGS targets.  Set no_install
	to true.  Add --disable-threads --disable-libasprintf.  Drop the
	lib_path (as there are no shared libs).

Afternoon,

This patch disables various targets and features on the gettext module
to fix problems reported by David Edelsohn and Eric Gallager in
https://inbox.sourceware.org/CAGWvnynmWgNjup4cAwSbsy1vw_MJLQqSULwM=kTH_+Lt+_smbg@mail.gmail.com/
and followups and on IRC, respectively.

The gettext module does not actually require any of these to be usable
for the purposes of the toolchain, so disabling them seems to be a
decent workaround.

This seemed to fix the respective issues for both Eric and David,
though, I could not get GDB to build on AIX with or without this patch
applied (I needed to disable sim, gdb and gnulib modules).

It is possible I am missing something.  Due to some unfortunate
circumstances, it's taken more time than anticipated to actually get
this change tested, and I've had to context swap quite a few bits.  Such
a process has quite a lot of room for error.

Tested on x86_64-unknown-freebsd13.2.
