When the asm-offset stuff were consolidated the mips variant
did not match the others.
I do not recall if I ever tried this on a mips tool-chain and as
my dev box is busted atm I cannot even test it out now.

I would be happy if we could kill the MIPS specific sed expression
in the top-level Kbuild file.

Ralf - can you take a look at this and see if mips really generates
different assembler syntax which warrants the different sed expression.

If mips really needs a different sed expression then we should adjust
it so the output is similar to the other archs.
