So ... Magnus, are you happy with the current state of the proposed patch?

feature tests are better than version tests. Because there are various
linkers in play (old GNU ld, gold, lld, macosx ld, BSD ld) and we'd like
our compilers to work the same way on various platforms, I'm vaguely
unhappy with TOOLCHAIN_MINIMUM_LD_VERSION_gcc. It looks
like TOOLCHAIN_EXTRACT_LD_VERSION is another place where we conflate
toolchains and operating systems.

As always, I am for portability and for toolchain competition. I'd like to
be able to build with Intel's icc toolchain.
