(NO_DOLLAR_IN_LABEL): Undef because gas understands dollars
in labels and gdb expects them if configured for gas.
(STARTFILE_SPEC): Include huge.o to be compatible with native cc.
(ASM_OUTPUT_CONSTRUCTOR, ASM_OUTPUT_DESTRUCTOR):
(CTOR_LISTS_DEFINED_EXTERNALLY, DO_GLOBAL_DTORS_BODY):
(STARTFILE_SPEC): Conditionally redefine for a collectless version
of gcc if USE_COLLECT2 is not defined.
