Correct mips arch in udpkg.

[Petter Reinholdtsen <pere@hungry.com>]

> Added missing alignment for array in endianess test.

What about this patch instead?  Less code, and checking the endianness
at compile time.

I placed the call to strcmp() last, to make it easier for the compiler
to optimize away the call on big endian machines.
