I have built a cross cc1/cc1plus with:

blah/configure --enable-languages=c,c++ --target=armv5tel-unknown-linux-gnueabi

but I get a totally different error on testsuite/gcc.target/arm/mmx-2.c, not
the unrecognized __builtin_arm* errors reported.  I get an IRA ice:

cp /source_dir/gcc/testsuite/gcc.target/arm/mmx-2.c a.c
./cc1 -quiet -mcpu=iwmmxt -flax-vector-conversions -std=gnu99 a.c -I /tmp
a.c: In function 'foo':
a.c:166:1: internal compiler error: in find_costs_and_classes, at
ira-costs.c:1710
 }

Unrecognized __builtin* sound like -mcpu=iwmmxt is not being passed to the
compiler command line.

Can you try "make check-gcc RUNTESTFLAGS=arm.exp" in your build/gcc directory
and attach the the entire gcc/testsuite/gcc/gcc.log file?

And just for kicks, could you include the result from:

/build_directory$ grep 'with options' config.status

and

/build_directory$ grep 'with options' gcc/config.status

This would help enormously, as I don't have an armv5tel machine to test on.

Thanks.
