* dbxread.c: Move default definition of GCC_COMPILED_FLAG_SYMBOL

Browse source 
from here . . .
	* symtab.h: . . . to here.
	* dbxread.c (record_minimal_symbol): Move check for gcc{,2}_compiled.
	and __gnu_compiled* from here . . .
	* minsyms.c (prim_record_minimal_symbol_and_info): . . . to here.
	* minsyms.c (prim_record_minimal_symbol): Call
	prim_record_minimal_symbol_and_info rather than duplicating code.
