This change saves/restores the callee-saved MIPS floating point registers as documented by the o32/n32/n64 spec ("MIPSpro N32 ABI Handbook", Table 2-1) for the _setjmp(3), _longjmp(3), setjmp(3) and longjmp(3) C library functions.

The #ifdef is per ngie's request; the includes are clearly necessary for struct stat.

| | | | | | | | | | | | | In ARM asm code, ensure that every ENTRY(foo) has a matching END(foo). The EABI unwind info requires a .fnend for every .fnstart, and newer binutils will complain about seeing two .fnstart in a row. This change allows newer tools to compile our code. Do not generate unwind info in asm functions if _STANDALONE is defined. The .fnend op causes the assembler to emit RELOC references to unwind support functions that don't exist in libstand.
