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-tracking-open-12.08-release/1//pinned-manifest.xml > .repo/manifest.xml

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:

https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AnpUtxWjZbP9dGg0dW5pdDl2T1lOUFk1aEktOFh0ZXc#gid=0

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
