Fix order of eh_frame sections in linker scripts
The compiler driver positions the linker script at the end of the linker
command-line, after crtend.o. As a result, any INPUT objects and archive
GROUPs introduced by the linker script are placed after crtend.o and the
end-of-frame marker provided by crtend.o ends up in between .eh_frames
instead of being at the end.
This has always been a problem, but a binutils update to clean-up
redundant NULL markers in .eh_frame exposes it as a execution failure in
exception-handling tests. This patch re-orders .eh_frames in all
MIPS linker scripts so that the one from crtend.o is always placed last.
