From Anatol Pomozov <anatol.pomozov@gmail.com>
Taken from Arch Linux arm-none-eabi-gcc package.
Modified version of ARM patch https://gcc.gnu.org/ml/gcc-patches/2012-05/msg00083/enable-with-multilib-list-for-arm.patch
This patch enables the use of the "--with-multilib-list" flag, when
configuring GCC 6.2. It makes GCC 6 compatible with the configure flags used
in the "gcc-arm-none-eabi-4.9" package.
