The right thing to do is what po/exgettext does:

# Set AWK if environment has not already set it.
AWK=${AWK-awk}

That will pick up the $(AWK) variable from the Makefile, which in turn
is set by the configure script to whichever of mawk, gawk, or nawk you
have.

For sort, don't use a variable at all.

I note that opts.sh has a localized override of LANG on the sort
invocation.  It would be a good idea to copy this bit from
po/exgettext instead:

# Always operate in the C locale.
LANG=C
LANGUAGE=C
LC_ALL=C
export LANG LANGUAGE LC_ALL
