PowerPC 32bit (ppc32) follows the System V ABI. This ABI does not specify
function descriptors for function pointers. Instead, the function pointer is a
scalar 32bit value.
The testcase Wtrampolines-3.c works fine when compiled with -m32. Hence the
correct fix would be:
{ xfail { powerpc*-*-* && lp64 } }
