Interesting case of different signature in TUNE_PKGARCH recipe

Found in:
meta-oe/meta-oe/recipes-multimedia/libdvdread/libdvdread_4.2.0.bb

this line:
CONFIGUREOPTS := "${@d.getVar('CONFIGUREOPTS', True).replace('--disable-silent-rules', ' ')}"

is able to trick variable tracking code to forget that STAGING_DIR_HOST is included in
BB_HASHBASE_WHITELIST, it came from:
meta/classes/autotools.bbclass:def append_libtool_sysroot(d):
   --with-libtool-sysroot=${STAGING_DIR_HOST}

So it behaves like with
CONFIGUREOPTS[vardepvalue] = "${CONFIGUREOPTS}"

And the result is:

Good news is that rewriting that line with new _remove operator as:
CONFIGUREOPTS_remove = "--disable-silent-rules"
makes signatures the same.

For curious people there is bitbake-diffsigs between old CONFIGUREOPTS line and new one:
