mips: fix build regression
mips: fix build regression

The recent commit (2690fadc8b35190dddd29274a7405bac13adc469) shuffled
the mips headers around causing it to check the ABI defines before it
included the header which set those up.  Now all mips builds fail with:
	In file included from count.c:36:0:
	defs.h:48:4: error: #error Unsupported _MIPS_SIM

* defs.h [MIPS]: Move sgidefs.h above _MIPS_SIM check.
