gmon-sol2.c: Silence compilation warnings by partially synchronizing code with...

	* config/i386/gmon-sol2.c: Silence compilation warnings by partially
	synchronizing code with config/sparc/gmon-sol2.c.  Remove #if 0
	blocks.  #include "tconfig.h" and "tsystem.h" to prototype system
	functions such as sbrk, write, etc..  Add function prototypes.
	Convert function declarations from K&R to ISO C.  Cast pointers
	to "long" and "unsigned long" instead of "int" and "unsigned int".
	Convert tokens following #endif into comments.
