It depends where per-targets flags have been added: compile was
used with your previous patch, it is not with the new one.

Presently when compile is used, it is hardcoded into CC, so it
is also used with libtool.

So it seems to me, although I'm not sure what your test is,
and AFAICT this is not the variable used by A[CM]_PROG_CC_C_O.
