Remove the board specific linker script. It is not
needed anymore, the unified MIPS linker script can
be used instead.
The qi_lb60 target produces a slightly different
image after the change than before. The value of
'num_got_entries' symbol is different:

This is caused by the different placement of the
'__got_start' and '__got_end' symbols between the
board specific scrip and the unified script.
board specific script:
__got_start = .;
.got : { *(.got) }
__got_end = .;
unified script:
.got : {
__got_start = .;
*(.got)
__got_end = .;
}
Despite this difference, the resulting images are
functionally identical.
