still playing, this is what I came up with at the end

SLKCFLAGS=${SLKCFLAGS:--O2}
LIBDIRSUFFIX=""
[ "$(uname -m)" = "x86_64" ] && SLKCFLAGS="$SLKCFLAGS -fPIC"
LIBDIRSUFFIX="64"
[ "$ARCH" = "i?86" ] || [ "$ARCH" = "native" ] && SLKCFLAGS="$SLKCFLAGS
-march=$ARCH"
[ "$ARCH" = "i686" ] && SLKCFLAGS="$SLKCFLAGS -mtune=$ARCH"
