Does not work for my configuration. The error when compiling gcc is:

  Unknown ABI used in --with-abi=aapcs-linux

The relevant bits from my .config are:

BR2_iwmmxt=y
BR2_ARM_TYPE="ARM_IWMMXT"
# BR2_ARM_OABI is not set
BR2_ARM_EABI=y
BR2_ARCH="arm"
BR2_ENDIAN="LITTLE"
BR2_GCC_TARGET_TUNE="iwmmxt"
BR2_GCC_TARGET_ARCH="iwmmxt"
BR2_GCC_TARGET_ABI="aapcs-linux"
BR2_GCC_VERSION="4.3.2"

Anything else you want me to try ?
