I'm afraid I don't understand this patch or the previous one (or
both?).  So this new Makefile knob stops hard-linking the dashed
builtins _during 'make install'_, but it doesn't affect how Git is
built by the default target.  And our CI jobs only build Git by the
default target, but don't run 'make install', so setting
SKIP_DASHED_BUILT_INS wouldn't have any affect anyway.

Note that the CI jobs executed in containers (Linux32 and linux-musl)
don't use this 'ci/run-build-and-tests.sh' script, so they won't set
SKIP_DASHED_BUILT_INS.  I suppose that's unintentional, because it
wasn't mentioned in the commit message.
