> make/common/NativeCompilation.gmk uses NM too, is there a reason to avoid the flag there? flags-other.m4 : the comment 'on AIX ...' is just stating the obvious; maybe it should better mention that without -X64 we only process 32bit objects ('Processes only 32-bit object files' says the manpage , and this is the default on AIX) ; or avoid the comment altogether ?

I didn't see these nm calls. I focused on the AIX specific only. Thanks for mentioning this. When are static libraries and mapfiles used? In addition I'm wondering how the nm call with the -m option in the else condition will work. This option is not known by all nm implementations, as I know.
I add the NMFLAGS to the missing nm calls, also for other target OS and improved the comment.
