xpcom/glue/ uses a generic 'arm' to check whether to build an ARM-specific object file or not.

The checks are done using "ifeq (arm,$(TARGET_CPU))", this would only work on Linux on those cases where the compiler has a CTARGET like arm-none-linux-gnueabi. Some other distros(gentoo, f.ex) use specific triplets for the different ARM subarchitectures, f.ex armv7a-unknown-linux-gnueabi, therefore making this check useless.

With the patch i'm attaching i'm doing the same approach as xpcom/reflect/xptcall/src/md/unix/, although in that case it uses OS_TEST and not TARGET_CPU, but the problem is the same as OS_TEST on ARM is ${target_cpu}.
