Re: Get rid of fprintf_vma and sprintf_vma

Commit f493c2174e messed the formatting in linker map files,
particularly for 32-bit builds where a number of tests using map files
regressed.  I should have noticed the BFD64 conditional printing of
spaces to line up output due to the original %V printing hex vmas with
16 digits when BFD64 and 8 digits when not.  Besides that, it is nicer
to print 32-bit vmas for 32-bit targets.  So change %V back to be
target dependent, now using bfd_sprintf_vma.  Since minfo doesn't
return the number of chars printed, that means some places that
currently use %V must instead sprintf to a buffer in order to find the
length printed.

	* ldmisc.h (print_spaces): Declare.
	(print_space): Change to a macro.
	* ldmisc.c (vfinfo): Use bfd_sprintf_vma for %V.  Tidy %W case.
	(print_space): Delete.
	(print_spaces): New function.
	* emultempl/aix.em (print_symbol): Use print_spaces.
	* ldctor.c (ldctor_build_sets): Likewise.
	* ldmain.c (add_archive_element): Likewise.
	* ldlang.c (print_one_symbol, lang_print_asneeded): Likewise.
	(print_output_section_statement, print_data_statement): Likewise.
	(print_reloc_statement, print_padding_statement): Likewise.
	(print_assignment): Likewise.  Also replace %V printing of vmas
	with printing to a buffer in order to properly format output.
	(print_input_section, lang_one_common): Likewise.
