[PATCH 2/5] MAKEALL: return error code from do_build_target

[Ahmad Fatoum]

The script currently records only if any config build failed to control
the exit code, but doesn't return an error code from each single
do_build_target. We need this though, when we start running the test
suite for successful builds, so let's add a return value and rename the
global ret variable to a more descriptive exitcode.
