Add explicit arch-specific modules.c rules to keep the build from generating an incorrect common/modules.c. Otherwise the pattern rules would cascade such that it'd look for $arch/modules.o which turned into common/modules.c which triggered the gen rule. My local testing of this code didn't catch this bug because of how Automake manages .Po (dependency files) in incremental builds -- it was adding extra rules that override the pattern rules which caused the build to generate correct modules.c files. But when building from a cold cache, the pattern rules would force common/modules.c to be used leading to crashes at runtime.
