app-portage/prefix-toolkit: new packageprefix-toolkit-0
* For any Gentoo Prefix, provides the 'startprefix' script, and should provide some 'runprefix' script later on, as inspired in Bug: https://bugs.gentoo.org/673816 * For base Gentoo Prefix (as in "not stacked"), provides the 'prefix-stack-setup' script, superseding app-portage/prefix-chain-setup, does force the prefix-stack implit USE flag in the stacked Prefix. * For stacked Gentoo Prefix (set up using 'prefix-stack-setup'), provides the toolchain wrapper, superseding sys-apps/prefix-chain-utils. Bug: https://bugs.gentoo.org/658572 Closes: https://bugs.gentoo.org/509142 Package-Manager: Portage-2.3.51, Repoman-2.3.11 Signed-off-by: Michael Haubenwallner <haubi@gentoo.org> (cherry picked from commit 84b9f582e8c8db69a3b3677de702c7cc00ac3dab)
