MIPS: uapi/asm/siginfo.h: Fix GCC 4.1.2 compilation
It wasn't until GCC 4.3 I believe that the __SIZEOF_*__ predefined macros were added. The change below switches <uapi/asm/siginfo.h> to the _MIPS_SZLONG macro so that compilation with e.g. GCC 4.1.2 succeeds. This is a user API header so I think this is even more important, for older userland support. The change adds an unsuccessful default too, to catch any compiler configuration oddities.
