[Bug other/35457] New: Error building GCC trunk on CELL SPU

[eres at il dot ibm dot com]

I get the following error message trying to build trunk r132854 on CELL
SPU:

-O2 ' 'CPPFLAGS=' 'LDFLAGS=' 'build_alias=powerpc64-unknown-linux-gnu'
'host_alias=spu' 'target_alias=spu' --cache-file=.././config.cache
--srcdir=../../../../gcc/newlib/libc
configure: loading cache .././config.cache
configure: error: `CFLAGS' has changed since the previous run:
configure:   former value:  -g -O2
configure:   current value: -g -O2
configure: error: changes in the environment can compromise the build
configure: error: run `make distclean' and/or `rm .././config.cache' and
start over
configure: error: /bin/sh '../../../../gcc/newlib/libc/configure' failed
for libc
make[1]: *** [configure-target-newlib] Error 1
make[1]: Leaving directory `/home/tehila/nfs/mainline_new/build_org'
make: *** [all] Error 2

It might be introduced by a recent change to the calculation of
CFLAGS_FOR_TARGET.
Deleting config.cache file does not seem to help.
