Adapted from the mplayer magic Graeme and I came up with some years ago:

#build with support for the iwmmxt instruction (pxa270 and up)
MY_ARCH := "${PACKAGE_ARCH}"
PACKAGE_ARCH = "${@base_contains('MACHINE_FEATURES', 'iwmmxt', 'iwmmxt',
'${MY_ARCH}',d)}"

QT_CONFIG_FLAGS_append = " ${@base_contains('MACHINE_FEATURES',
'iwmmxt', ' -iwmmxt', '',d)} "
