Originally the test for _'s on symbols was not done when cross-compiling and
it was assumed that the _'s were appended. The test does in fact work since
it simply compiles a file and then run's nm on it. So patch this to enable.
Without this x86 targets fail during linking since the assembler code has
the _'s appended when it shouldn't.
