scons: Add a "mold" value to the --linker option.
This new and improved linker approximately halves link time for
build/X86/gem5.opt for me compared to lld, the previously fastest
linker. The -fuse-ld=mold option is supported by current versions of
clang, and will be supported in gcc 12.
To use the mold linker with gcc prior to version 12, you need to set
the LINKFLAGS_EXTRA scons variable to pass in a -B option as described
on this page:
