Improved MIPS/Linux gc_os_dep.c definitions

Browse source 
From Thiemo Seufer <ths@networkno.de>:

	* gc_os_dep.c (CPP_WORDSZ, ALIGN_DOUBLE, DATAEND,
	DYNAMIC_LOADING): Added #defines.
	(_fdata, _end): Added declarations.
	(DATASTART): Use _fdata instead of __data_start.
	(STACKBOTTOM): Changed from 0x80000000 to 0x7fff8000.
