[Bug bootstrap/26628] New: Build fails trying to run ppc64 binaries on powerpc-apple-darwin8.5.0

["malcolmpurvis at optushome dot com dot au" <gcc-bugzilla at gcc dot gnu dot org>]

I've been trying to build the official 4.1.0 release on my G3 and G4 MacOS
10.4.5 systems with the configure command:

$ ../gcc-4.1.0/configure --prefix=/Users/malcolmp/prefix/gcc-4.1-world

This eventually fails when trying to build libstdc++-v3.  The last few lines of
output are:

If you meant to cross compile, use `--host'.

--------------------------------------------------------------------------------

It looks like configure is performing a test compile with 'xgcc -m64' and
trying to run the result.  Obviously this fails on these 32-bit cpus.

The same source and the same configure flags builds without error on my 10.4.5
G5 system.
