Fix libatomic multilib parallel build (PR other/67627)
The all-multi target may be built in parallel with the %_.lo
targets which generate make dependencies that are parsed during
the build of all-multi.
This patch forces all-multi to only run after the *_.lo targets
are done.
libatomic:
PR other/67627
* Makefile.am (all-multi): Add dependency.
* Makefile.in: Regenerate.
