In case of Linux/MIPS it could guess wether it's a little endian or big
endian configuration and emit mips-unknown-gnu-linux or
mipsel-unknown-gnu-linux that is taking away the burden of the user knowing
about the right endianess for his target - specifying mips-linux as target
should then be sufficient. Does that sound sane or would overriding the
users explicitly give targetname (or even hostname for a native build) be
considered a bad thing?
