Why does isomac use -D_LIBC for its header examinations at all? That
doesn't seem appropriate, since it should be testing the headers as seen by
a user program. If _LIBC is needed for some reason in the libc build
environment, it should use -DNOT_IN_libc to avoid the internal magic.

I don not remember anymore why it was added but there was a reason. You
probably can rediscover it by simply removing the #define.

Because <gnu/stubs.h> does not exist until after installation. It is
generated on the fly by the toplevel makefile.
