As opposed to other architectures, on MIPS gcc toolchain provided
gcclib is not always adequate, for instance when the library does not
account for the case when data segment is too large to fit into the
64K GOT.
Let's make sure the library is not included when building for MIPS
targets.
BRANCH=none
BUG=chrome-os-partner:31438
TEST=with the rest of patches applied the FPGA board boots all the way
to verifying and loading the kernel from the USB stick.
