CMake: add WITH_LINKER_MOLD option for GCC/Clang Unix platforms
Can give considerably faster linking, especially on system with many
cores.
The mold linker recently reached 1.0, see:
https://github.com/rui314/mold
The current stable release of GCC can't use this linker via
-fuse-ld=mold, so this patch uses the "-B" argument to add a binary
directory containing an alternate "ld" command that points to
"mold" (which is part of the default mold installation).
Some timing tests for linking full builds for AMD TR 3970X:
- BFD: 20.78 seconds.
- LLD: 12.16 seconds.
- GOLD: 7.21 seconds.
- MOLD: 2.53 seconds.
