re PR target/34484 (libgcc should check if feclearexcept (and others) available for BID support on uclibc) 

PR debug/34484
	* dwarf2out.c (dwarf2out_switch_text_section): Do not guard with
	DWARF2_DEBUGGING_INFO.
	(dwarf2out_note_section_used): Ditto.  Add prototype.
	(have_multiple_function_sections, text_section_used,
	cold_text_section_used, *cold_text_sections): Move declarations
	before their uses.
