looks fine to me. checked with a gcc build on the 4.5 branch.

If this is checked in on the trunk, I would like to ask to apply it to the 
branch as well.  Selection of the linker currenly is only possible with the 
-B<path> option and some locally created symlinks in directories not on PATH. 
The -B<path> is installation dependent, your patch does remove this dependency.

Even one of our release managers mentioed that he would use a specfile 
patch/hack to be able to select another linker ;)
