[Bug driver/29931] New: following argv[0] symlink in process_command breaks symlinked-together toolchain

["amylaar at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

We (STM) create a directory which has symlinks to gcc and other tools and
related libraries, and these symlinks point to different places.
The current behaviour of gcc is to follow the gcc link, from where it won't be
able to find the other tools, nor the libraries.
