Subject: MIPS: Build microMIPS VDSO for microMIPS kernels

From: James Hogan <james.hogan@imgtec.com>

commit bb93078e655be1e24d68f28f2756676e62c037ce upstream.

MicroMIPS kernels may be expected to run on microMIPS only cores which
don't support the normal MIPS instruction set, so be sure to pass the
-mmicromips flag through to the VDSO cflags.
