Alan Modra 6f8f95b4c4 Large memory allocation reading fuzzed 64-bit archive
This patch adds a sanity check for the size of an armap.

	* archive64.c (_bfd_archive_64_bit_slurp_armap): Check parsed_size
	against file size before allocating memory.  Use bfd_alloc rather
	than bfd_zalloc for carsym/strings memory.

Alan Modra dc1e8a474f Indent labels
Labels don't go in the first column according to standard emacs C
indent rules, and I got annoyed enough at seeing diff -p show a label
rather than the function name to fix this.

Alan Modra 806470a219 Miscellaneous memory alloc related fixes
Some minor tidies.  Allocating memory for internal relocs and symbols

H.J. Lu e6cc316af9 Enable 64-bit archives in ar and ranlib
Since existing ld and gold support the 64-bit (MIPS) ELF archives, we
can use the 64-bit (MIPS) ELF archives as 64-bit archives.  Since the
plugin target is used to create archive in plugin-enabled ar, we need
a way to enable 64-bit archives in the plugin target.  This patch adds
--enable-64-bit-archive to bfd to force 64-bit archives in ar and
ranlib.  Since both 64-bit MIPS and s390 ELF targets currently use
64-bit archives, 64-bit archives are enabled by default for them.
64-bit archive is generated automatically if the archive is too big.

Tested on Linux/x86 and Linux/x86-64 with existing ld and gold.
