* configure.ac (gcc_cv_gold_srcdir): New cached variable -
contains the location of the gold sources.
(ORIGINAL_GOLD_FOR_TARGET): New substituted variable - contains
the name of the locally built gold executable.
* configure: Regenerate.
* collect2.c (main): Detect the -use-gold and -use-ld switches
and select the appropriate linker, if found.
If a linker cannot be found and collect2 is executing in
verbose mode then report the search paths examined.
* exec-tool.in: Detect the -use-gold and -use-ld switches and
select the appropriate linker, if found.
Add support for -v switch.
Report problems locating linker executable.
* gcc.c (LINK_COMMAND_SPEC): Translate -fuse-ld=gold into
-use-gold and -fuse-ld=bfd into -use-ld.
* common.opt: Add fuse-ld=gold and fuse-ld=bfd.
* opts.c (comman_handle_option): Ignore -fuse-ld=gold and
-fuse-ld=bfd.
* doc/invoke.texi: Document the new options.
