[PATCH 1/5] libgloss: aarch64: delete unused multi-build logic

[Mike Frysinger]

This logic looks like it was copied from the arm port, but it isn't
actually used here.  Since no other port uses this custom libgloss
multi-build.in logic, and it's making things difficult to unify,
and aarch64 isn't even using it, drop it all.  The set of installed
objects and their content should be the same.

Once we move this to unified automake, if we want to readd support
for subdir multi-builds, it'll be a lot easier as we can just add
another set of objects with custom flags.

None of this should be confused with the common multilib logic.
This *multi-build* which is processed in parallel.
