This is wrong.  "uname" does not tell you the machine architecture;
"uname -m" does, at least on my PowerPC Macs.  Also:

$ sysctl hw.cpu64bit_capable
second level name cpu64bit_capable in hw.cpu64bit_capable is invalid

This is also wrong.  ppc-elf is neither a canonical nor a common prefix.
Whoever built your toolchain was hellbent on making life difficult for
the users of said toolchain.

Not everyone wants to see your debug output, did you forget to remove  
it?
