failures in gcc tests when multiple cpu cflags specified

[Joel Sherrill]

Hi,

Janis wanted a recap on this list.  The thread
starts here:

http://gcc.gnu.org/ml/gcc/2008-04/msg00587.html

And this is the last message in the thread which
sums up the expert views:

http://gcc.gnu.org/ml/gcc/2008-04/msg00708.html

The latest powerpc-rtems4.10 GCC test results
are here:

http://gcc.gnu.org/ml/gcc-testresults/2008-12/msg01477.html

The tests in question are "scan-assembler" and
other tests which specify a particular -mcpu option
which conflicts with those used by the particular
target hardware we are running on.

So for example, a test may try to verify that
gcc generates a particular instruction on a
ppc405.  But the specific board cflags
are explicitly selecting another -mcpu so the
code can actually work on the target board.
