Subject: build: remove mucking with CARCHFLAGS

We've never received an update to this, and gcc has sane defaults out of
the box anyway, as do most projects in their build systems. Remove the
magic here and just let downstream distros handle any changes or
additions necessary, as we already do for LDFLAGS.
