libgloss: document & localize custom multi-do rule
The multi-build.in file in libgloss duplicates common multilib logic
in the root source tree. Document it a bit, and rename the rule so
it doesn't clash with the common multi-do rule. This will let us use
them in the same makefile so we can merge aarch64/ & arm/ up (as the
only targets that use this local multi-build.in atm).
