Ouch, we do not call cc in any of the perl code, that is sure, but
you are right, we ship the config.guess for detecting the platform.

That happens in
for all but Windows. The code is:
    if ($^O =~ /^MSWin/i) {
      $::_platform_ = "win32";
    } else {
      my $config_guess = "$::installerdir/tlpkg/installer/config.guess";

This is again called from
which *checks* first if the texlive.tlpdb setting "platform" is 

Unfortunately be default the platform is *not* written into the
tlpdb. This way the installation becomes more portable
(Think about an installation that has two sets of binaries and
no platofrm settings. In this case I can run tlmgr from both 
archs without problem - but I must say, I have never tried).

The platform setting is only saved into the tlpdb during installation
time when the architecture is forced.

Now, how can one circumvent this ... it is documented:
	tlmgr platform set <preferred_platform>

After this tlmgr should not use config.guess anymore ....

Hope that helps. If you need anything else, let me know.

If there is a different and save way to get the platform name on
Apple, let me know. We trued a lot of different things, but none
of them worked on all supported archs/os combinations.
