libffi standalone

[Timothy Wall]

Before expending any effort to post a standalone build patch, I'd  
like to gauge the interest in this.  Python ctypes has at least three  
branches of libffi; there are probably other projects (I'd cross-post  
to the python lists but they seem to be member-only).

I think the bulk of it consists of reviving a number of files removed  
circa 2000, namely:

Only in libffi: config-ml.in
Only in libffi: config.guess
Only in libffi: config.sub
Only in libffi: depcomp
Only in libffi: install-sh
Only in libffi: ltcf-c.sh
Only in libffi: ltconfig
Only in libffi: ltmain.sh
Only in libffi: missing

Plus one or two minor tweaks to "configure" to get the right $srcdir  
value and suppress superficial warnings.
