Koen suggested other solution - marking packages MACHINE specific when
COMBINED_FEATURES are used. For example wpa-supplicant will get this:

DEPENDS = "gnutls ${@base_contains('COMBINED_FEATURES', 'pci', 'madwifi-ng', '',d)}"
PACKAGE_ARCH = "${@base_contains('COMBINED_FEATURES', 'pci', ${MACHINE}, ${TARGET_ARCH}, d)}"

export HAS_PCI = ${@base_contains('COMBINED_FEATURES', 'pci', 1, 0,d)}

do_configure () {
        install -m 0755 ${WORKDIR}/defconfig-gnutls  .config

        if [ "x$HAS_PCI" == "x1" ] then; do
                echo "CONFIG_DRIVER_MADWIFI=y" >> .config
                echo "CFLAGS += -I${STAGING_INCDIR}/madwifi-ng" >> .config
        fi
}

Opinions?
