libgloss: arm: inline multi-build logic

Since no other port uses this custom libgloss multi-build.in logic,
and it's making things difficult to unify, drop it all.  The set of
installed objects and their content should be the same.

There is a difference in the builds: currently we compile all the
objects in this subdir twice, but only a subset of them use a diff
set of flags, and are actually installed (the librdimon.a and its
objects).  So this change speeds things up by removing the duplicate
compilation.

There is a short term cost in having to duplicate the compile rules
for the files that are different, but this is minor when compared to
being able to delete the unused multi-build logic (which we'll do in
a sep commit), and we'll be able to clean this up when we move the
code to unified automake.

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