Left-over part of commit 84b2a020daa17d8ee5c9ec979c3d56f95e69573b
The _end marker must be aligned to 4-bytes to ensure that the last
element written does not reach beyond the address of _end. This is
also necessary as the termination condition is an equality test
instead of an ordered test so (_end - _fbss) must be a multiple of
4-bytes. The alignment is already correct for mti*.ld files, fix
it for all remaining MIPS scripts that don't already align to at
least 4.

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.
