When developing the patch to use the linker plugin only if the (plugin)
linker supports it, I had neglected to check for targets that defined
their own version of LD_COMMAND_SPEC. Of course, this couldn't go
unpunished, since there are two of them:
* Darwin has its own version in config/darwin.h. This is updated by the
following patch.
* The only other affected target is DJGPP (i[34567]86-pc-msdosdjgpp*),
but config/i386/djgpp.has no provisions for LTO at all, so I'm not
touching that.
The (almost obvious) patch was tested by Iain on *-darwin9 and by
Dominique on x86_64-darwin10.
Approved by Mike in the PR, installed on mainline.
