[gentoo-pms] [PATCH v4] pkg-mgr-commands: Add --build and --target to econf (retroactively)

["Michał Górny" <mgorny@gentoo.org>]

Amend the econf parameter list with --build and --target options
corresponding to CBUILD and CTARGET variables respectively. They are
useful for cross-compilation purposes (whose support is improved
in EAPI 7), and all three package managers have been passing them dating
back at least to 2005 and/or their inception appropriately.
