patch to take he LD_RUN_PATH environment variable into account

Contrary to the conventional linker, gold doesn't take the LD_RUN_PATH
environment variable into account (default runpath). I've reported a bug
against Debian here:

  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=660813

and Jonathan Nieder posted a patch, which I've tested and solves the problem
I've reported. It is attached.

The ld(1) man page should also mention it. The old ld(1) man page says:
* For -rpath=dir: If -rpath is not used when linking an ELF executable, the
contents of the environment variable "LD_RUN_PATH" will be used if it is
defined.
* For -rpath-link=dir: On an ELF system, for native linkers, if the -rpath and
-rpath-link options were not used, search the contents of the environment
variable "LD_RUN_PATH".
But it could be better to describe it in an ENVIRONMENT section, where
environment variables are usually described.
