No, your log indicates them to be correct.

 maintainer-mode (configure --enable-maintainer-mode).

* The CFLAGS you are using are dubious:
-mcpu=750 -D__ALTIVEC__ -Wa,-m7450

Seems to me as if you are trying to outsmart an older GCC, which does
not support the 7450, to "fake" the m7500.

I'd recommend you to start anew (remove the build directory),
bootstrap the source-tree and configure with --enable-maintainer-mode.
Also make sure not to have set any PROJECT_* variable in your
environment or in your <BSP>.cfg.

Symptoms of a failed "make preinstall".

Where does this come from? This is not supposed to be there.

This one is the only one which is of any importance.

I can't reproduce your issue.

Wasn't it you who had problems with a broken m4?

Your symptoms also can be symptoms of a broken m4 or sed.
