I hear you.

My current thinking is that I'm going to introduce a configure argument, 
something like --with-toolchain-linker=gold, and if it is enabled, I'll 
verify that gold is indeed present, and if it supports --threads. It 
will be available on all gcc platforms.

This will take some more time to write than my initial one-liner, so 
I'll take this back to the drawing board for awhile.
