Turn off the "-O2 flag TRIGGERS KNOWN OPTIMIZER BUGS" warning.

Browse Source 
From current testsuite results, the optimizer bugs don't appear to exist
anymore.  RTH@cygnus.com did a lot of work on the Alpha ELF code generator
for GCC 3.2[.0].  A recent FreeBSD/AXP GCC bootstrap is at
http://gcc.gnu.org/ml/gcc-testresults/2002-09/msg00604.html
In this bootstraps, all gcc libraries are built with -O2 and c-torture
gives -O2 a real workout.  None of the remaining failures have anything
to do with -O2 optimizer bugs.
