Tested with 2015 q3 release:

https://launchpad.net/gcc-arm-embedded/4.9/4.9-2015-q3-update

Hi tgarc,
I'm new to this stuff. How can I apply the patch to "gcc-arm-none-eabi-4_9-2015q3" I've downloaded? If I try to apply the patch:

$ git apply be8.patch
error: build-toolchain.sh: No such file or directory
error: build-common.sh: No such file or directory
error: build-toolchain.sh: No such file or directory

My understanding Is the patch must be applied to some other tool which generates the arm toolchain. Can I use this build tool: https://github.com/ARMinARM/arm-toolchain-build-scripts and apply the patch to it?

ok I tried following the instructions in the link (https://launchpad.net/gcc-arm-embedded/4.9/4.9-2015-q3-update) you posted and I get this error:
