mmake passes $(CFLAGS_FOR_PIC), which is set to @CFLAGS_FOR_PIC@,
which is set by configure to `-fpic -DPIC_REG' or whatever is
appropriate for the platform in question.  On some platforms
it is set to nothing, since `-fpic' is the default (on those
platforms -DPIC_REG does nothing).

Passing only "--pic-reg" would be wrong, because "--pic-reg"
is equivalent to only to "-DPIC"; it does not include "-fpic".
