No, I don't think flags-other.m4 is suited. If at all, it should be handled in toolchain.m4 if we understand the -X64 flag on AIX as unconditional for every nm call. Then we could also remove -X64 in JvmMapFile.gmk.

Also, maybe we should check if we can remove BUILD_NM and/or unify BUILD_NM and NM - as I see it now, BUILD_NM is not used anywhere. But I don't know all the history and maybe I'm overseeing something.

OTOH, this cleanup could be done in another PR. For now, the code as it is would be ok, too.
