Absolutely. What you found in configure.tgt is a pattern-matching
string. That section of the configure file will be used for any target
that follows the pattern given, i.e. powerpc-(anything)-eabi. Normally,
the middle part of the triplet would be the product manufacturer, so you
might have powerpc-motorolamvme-eabi, or you might say powerpc-unknown-eabi:
both will be matched by the pattern powerpc-*-eabi. However since the
target name is used to make a subdirectory in the build tree (and later a
directory in the install tree) you cannot have pattern matching chars in it.
The bash shell would be confused when it saw 'mkdir powerpc-*-eabi' because
it isn't a valid filename.

That was the wrong thing to do. What you should have done was use a
target like powerpc-unknown-eabi in the configure command; then the section
of configure.tgt would match it correctly and everything would be OK because
you didn't use a * in your configure target.

I guess you got lucky; binutils is a fairly robust package!

Yep, you've got the answer there. First reverse the changes you made in
configure.tgt, then just to be sure rebuild and install binutils with the
powerpc-unknown-eabi target (so as to be sure the powerpc-unknown-eabi-gcc
will match up with it correctly). Finally try building gcc again.
