For added whitespace-damaged google-juice:

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

MY_TARGET_CC_ARCH := "${TARGET_CC_ARCH}"

- -mtune=iwmmxt', '${MY_TARGET_CC_ARCH}',d)}"
