[PATCH] MIPS: Revert 25c3000300163e2ebf68d94425088de35ead3d76

[David Daney <ddaney@caviumnetworks.com>]

Commit 25c3000300163e2ebf68d94425088de35ead3d76 added an ugly work
around for a bug in binutils 2.19 that was needed for Cavium Octeon
processor support.  Now binutils 2.19.1 have been released and the
work around is no longer necessary.

Since Cavium Octeon processor support has not yet been part of any
official kernel release, there is no need to maintain compatibility
with older toolchains.  We can simply say that only binutils 2.19.1 or
later is supported (instead of 2.19 or later as it was before).
