[PATCH] fix testsuite

I found the issue: newlib/testsuite/lib/passfail.exp was using a the 
function `newlib_target_compile` which is defined in newlib.exp but 
hasn't been included yet.

I attached a patch.

Still some tests fail to compile, but that seems more like an issue with 
the host environment or target board.


Cheers
