* linespec.c: Include "target.h".

	(minsym_found): Handle minimal symbols pointing to function
	descriptors.  Use find_function_start_pc.
	* minsyms.c (msymbol_objfile): New function.
	* parse.c (write_exp_msymbol): Handle minimal symbols pointing
	to function descriptors.
	* symtab.c (fixup_section): Only use minimal symbol at the same
	address to determine section of a symbol.
	(find_function_start_pc): New function.
	(find_function_start_sal): Use it.
	* symtab.h (msymbol_objfile): Add prototype.
	(find_function_start_pc): Likewise.
	* value.c: Include "objfiles.h".
	(value_fn_field): Handle minimal symbols pointing to function
	descriptors.
	* Makefile.in (linespec.o): Update dependencies.
	(value.o): Likewise.
