* ldexp.h, ldlang.h: Change enum boolean -> enum bfd_boolean.

* ldtemplate: Remove ldfile_add_library_path calls;
	just use the SEARCH_DIR commands in the script files.
	* Makefile.in: Add LIB_PATH macro, which if set is used to replace
	the SEARCH_DIR commands in the scripts (using ugly sed magic).
	This is primarily intended for cross-linking, where you would
	place libaries in a different place than native libraries.
	Also, emulations made from ldtemplate now use $(srcdir).
	* ldglda29k.sc: Change SEARCH_DIR commands to a conventional
	form; people can use the Makefile's LIB_PATH to override.
