But the process is similar.
Please try my hack based on Linaro crosstool-ng Canadian windows build.
(1) wget
http://cbuild.validation.linaro.org/snapshots/crosstool-ng-linaro-1.13.1-4.8-2014.02.tar.bz2
(2) tar -xf crosstool-ng-linaro-1.13.1-4.8-2014.02.tar.bz2
(3) cd crosstool-ng-linaro-1.13.1-4.8-2014.02
(4) patch -p1 < hack.patch (attached. It changes HOST from
i586-mingw32msvc to arm-linux-gnueabi)
(5) make -f contrib/linaro/build.mk TARGETS=arm-linux-gnueabi
Please ignore the fails at the end to package windows staffs. And you
will get a toolchain at
./builds/arm-linux-gnueabi-win32/install
To build your gcc,
(1) Replace the gcc-linaro-4.8-2014.02 at
./builds/arm-linux-gnueabi-win32/.build/src
(2) Remove builds/stamp/arm-linux-gnueabi-win32-build
(3) make -f contrib/linaro/build.mk TARGETS=arm-linux-gnueabi
Good luck!
