This is what I came to do yesterday, but got distracted by the fact that it had been broken.

# Ensure that we're always using the adb in the tree. This works around the fact
# that bash caches $PATH lookups, so if you use adb before lunching/building the
# one in your tree, you'll continue to get /usr/bin/adb or whatever even after
# you have the one from your current tree on your path. Historically this would
# cause confusion because glinux had adb in /usr/bin/ by default, though that
# doesn't appear to be the case on my rodete hosts; it is however still the case
# that my Mac has /usr/local/bin/adb installed by default and on the default
# path.
