    xcompile: improve mips toolchain handling
    
    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
     CC_mips:=mips-linux-gnu-gcc
     CFLAGS_mips:= -Wno-unused-but-set-variable  -fno-stack-protector -Wl,--build-id=none -mno-abicalls -fno-pic -EL
     CPP_mips:=mips-linux-gnu-cpp
     AS_mips:=mips-linux-gnu-as
     LD_mips:=mips-linux-gnu-ld
     NM_mips:=mips-linux-gnu-nm

     READELF_mips:=mips-linux-gnu-readelf
     STRIP_mips:=mips-linux-gnu-strip
