[committed] Fix m68k testcase for c99

[Jeff Law]

More fallout from the c99 conversion.   The m68k specific test pr63347.c 
calls exit and abort without a prototype in scope.  This patch turns 
them into __builtin calls avoiding the error.

Bootstrapped and regression tested on m68k-linux-gnu, pushed to the trunk.
