[PATCH] ppc32: discard *.exit.text and *.exit.data sections

Browse Source 
Discard *.exit.text sections on runtime.  We cannot do this on link time
because of the way BUG macros are implemented.  If "__exit function" calls
one of those macros, __bug_table section will reference this function.
This is similar to ".altinstructions" situation on i386.

*.exit.data seems to be OK in this respect and is discarded on link
time.
