When I suggested this, I was thinking of the following type code that
is already in makepkg (line 659):
  # use ccache if it is requested (check buildenv and PKGBUILD opts)
  if [ "$(check_buildenv ccache)" = "y" -a "$(check_option ccache)" !=
"n" ]; then
    [ -d /usr/lib/ccache/bin ] && export PATH="/usr/lib/ccache/bin:$PATH"

Note that ccache is a BUILDENV var in makepkg.conf, but can still be
denied in a PKGBUILD by using !ccache (for those packages that don't
build correctly with it). I feel like a if clause just like the above
would work for xdelta as well (and cut your patch from -1/+3 to
