app-portage/prefix-toolkit (prefix-stack-setup): revbump
We do not want to have CBUILD build deps in prefix-stack, but CHOST build deps only. Since EAPI 7 there is BDEPEND, but EAPI 6 and older have both CBUILD and CHOST build deps in DEPEND. As most CHOST build deps also are in RDEPEND anyway, we omit EAPI 6 DEPEND from prefix-stack by setting EMERGE_DEFAULT_OPTS="--root-deps=rdeps" - ignored for EAPI 7.
