I played a little with it

SLKCFLAGS=${SLKCFLAGS:--O2}
LIBDIRSUFFIX=""
[ "$ARCH" = "x86_64" ] || [ "$ARCH" = "native" -a "$(uname -m)" = "x86_64"
] \
  && SLKCFLAGS="$SLKCFLAGS -fPIC" ; LIBDIRSUFFIX="64"
[ "$ARCH" = "i486" ] || [ "$ARCH" = "native" ] \
  && SLKCFLAGS="$SLKCFLAGS -march=$ARCH"
[ "$ARCH" = "i686" ] && SLKCFLAGS="$SLKCFLAGS -march=$ARCH -mtune=$ARCH"
