Alan Modra a6637ec0ed * budemang.c: New file, "demangle" function.
* budemang.h: New file.
	* addr2line.c (translate_addresses): Use "demangle".
	* nm.c (print_symname): Likewise.
	* objdump.c (objdump_print_symname): Likewise.
	(dump_symbols): Likewise.  Also, don't use bfd_asymbol_name macro
	here since that obfuscates.
	* rdcoff.c: Don't #include demangle.h.
	* Makefile.am (CFILES): Add budemang.c, emul_aix.c,
	emul_vanilla.c.  Remove emul_$(EMULATION).c.  Sort.
	(HFILES): Add budemang.h.  Sort.
	(nm_new_SOURCES, objdump_SOURCES, addr2line_SOURCES): Add budemang.c.
	Run "make dep-am".
	* Makefile.in: Regenerate.
	* po/POTFILES.in: Regenerate.
