Some ports depend on permissive or broken behaviour from the GNU BFD linker, ld.bfd. Clang and GCC support a -fuse-ld= flag to choose a specific linker, and as we migrate to installing lld as the base system /usr/bin/ld we'll want to make use of -fuse-ld=bfd to use bfd for ports that fail to link, or fail to run when linked with lld. An upstream libtool change[1] from Feb 2016 supports passing through -fuse-ld=, but it has not yet made it into a release. Patch an equivalent change into ltmain.sh via Mk/Uses/libtool.mk. Original proposal just patched ltmain.sh in devel/libtool. That would address ports that run libtoolize via autoreconf, including lang/mono which is one of the ports that fails to link with lld and responsible for many downstream skipped ports. Patching ltmain.sh via libtool.mk (tijl's suggestion) handles that case as well as ports that include their own copy of ltmain.sh. A later change may patch devel/libtool so that -fuse-ld works if using a ports-installed libtool to build software outside of the ports tree; the change in this commit is intended to address building in the ports tree.

# Valid args: keepla Don't remove libtool libraries (*.la) from the stage

# build Add a build dependency on devel/libtool. This can

# be used when a port does not generate its own libtool

# script and relies on the system to provide one.
