Target Milestone: ---
Target: powerpc
+++ This bug was initially created as a clone of Bug #108240 +++
Currently for the explicitly given option -m64 and the cpu type without
powerpc64 support like cpu 401, we just go with -m64 and powerpc64 enabled and
there is no any warnings or errors. Without any explicit option -m64 or -m32
but it's set as 64bit env from TARGET_DEFAULT, for the cpu type without
powerpc64 support like cpu 401, we will emit errors on Linux and warnings on
aix and darwin.
As Segher pointed out in PR108240, we've better to make them be handled
consistently, that is to raise errors and prevent this non-sense usage, open
this for further tracking.
