Revert from USE_LIBTOOL to binutil's own libtool, as libtool13 could
not grok the --without-pic option, and the configure script is not
prepared to handle libtool15 (yet) which in turn could have understood
--without-pic. Sigh. At least, that way we can avoid the overhead
of building all the unneeded shared libs.
Still, libtool insists on installing libbfd.la. As this file is really
small, I give in, and added it to pkg-plist.
GNU binutils. It can read/write about any object file format on earth.
Soon to be used by devel/avarice.
Requires devel/gnulibiberty, since it (alas) uses undocumented internal
functions from that library.
