The mips toolchain used by coreboot so far comes from Chrome OS chroot
and is built explicitly for little endian code generation.
Other flavors of MIPS toolchain usually generate big endian code by
default and require command line options to switch to little endian
mode.
This patch adds another variable to the set of compiler flags examined
to determine compiler compatibility. This results in adding another
nested for loop in test_architecture(). To avoid the need to break
from different levels of nesting, processing of the successful case is
taken out from test_architecture().
With this change the Mentor Graphics provided mips GCC toolchain is
accepted by xcompile, resulting in the following output:
ARCH_SUPPORTED+=mips
SUBARCH_SUPPORTED+=mips mipsel
