Hi,
It seems bug 947111 affects the binary toolchain.
---------- Forwarded message ---------- linaro-kernel seems to fail to build with the GCC4.7 [4.7.1 20120402 prerelease ] picked up from http://releases.linaro.org/12.04/components/toolchain/binaries/gcc-linaro-ar.... Here is the link to the job which failed https://ci.linaro.org/jenkins/job/linux-linaro-tracking_panda-omap2plus_sand...
This issue had been recorded previously with bug https://bugs.launchpad.net/ubuntu/+source/armel-cross-toolchain-base/+bug/94.... This appeared to be fixed already according to the bug report, but seem to have regressed again.
