Patch to fix the problem

There are two problems here.

The first problem is the segmentation fault if the builtin function does not
have an implicit function.  The patch adds code to return NULL_TREE in this
case, rather than cause a segmentation violation due to a NULL pointer.

However, in the case of powerpc-none-eabi, the vsx-mass-1.c test would still
fail, since some of the builtin functions are not treated as builtin (such as
atan2, which is what caused the fault).  Since the MASS library is only
available for powerpc Linux, I have restricted the test to only run on
powerpc*-*-linux*.
