There are many that use AC_CHECK_TOOL and the like, so you'd need to make
it a ${target_alias}-ar script (and likewise for ranlib).  Then there is
the GCC build, which might do that or might do something far more difficult
to figure out.  This is probably doable--more doable than getting a setting
of AR, or harder yet, of the flags passed to AR through configure/make for
the GCC build.  But it's a hell of a lot less friendly and replicable than
just setting an environment variable or configuring the target binutils
with --enable-deterministic-archives.


Thanks,
