Faraz Shahbazker a9a0d219a4 Make .data section placement coincide with _fdata symbol 
The _fdata symbol in MIPS linker scripts is aligned to a 16-byte
boundary.  The ALIGN function does not implicitly update current
location counter.  If sections positioned after the assignment
do not have the same natural alignment as the ALIGN function then
the start of the section group will not coincide with the value
of the symbol.

Given the linker command sequence:
  symbol = ALIGN (NN);
  (.section*)
where the idiom implies a desire to mark the beginning of .section
with symbol, there must be an assignment to the location counter
between the assignment to symbol and the .section pattern.

Faraz Shahbazker ab2901c843 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.

	* mips/array.ld: Re-order to place .eh_frame from crtend.o
	after all other .eh_frame sections.
