For people trying to build Linaro Android 12.08 there's an issue with an unknown reference in powertop2.0.
Here's what to do:
cd android edit .repo/manifest.xml
Find:
<project groups="path:external/powertop,name:tools/powertop-2.0" name="tools/powertop-2.0" path="exter\ nal/powertop" remote="linaro-other" revision="c80f55d9d1b823b7f6ff447eefc8a6ba04b939c4"/>
...and remove the line. Then
cp .repo/manifest.xml ../ cd .. rm -rf android/
edit linaro_android_build_cmds.sh
and change
curl -k http://snapshots.linaro.org/android/~linaro-android/vexpress-jb-gcc47-armlt-...
.repo/manifest.xml
to
cp ../manifest.xml .repo/
and rerun linaro_android_build_cmds.sh
You can also take a tip build which is not susceptible to this problem. Tip builds that have been booted are listed at:

If you still get errors after this, then its a general git timeout error. Just delete the android/ directory and start again or cd android/; repo ./sync
