Not at the moment.  The build was done with the --with-arch=2.0 to
check 32-bit PA2.0 code generation.  I don't usually configure with
this option.

I note the test uses __builtin_return_address (1).  This may not behave
correctly.

The test didn't fail on hppa-linux with --with-arch=2.0.  However, there
are differences in call stubs.  This is what makes  
__builtin_return_address
difficult.

Needs some debugging.
