I am trying to build cyanogenmod, but the build fails with the following. My drive on /mnt has plenty of space, however the root-partition where /tmp resides has less space, so I assume this happens while writing a temporary file.
Therefore I would like to redirect the temporary directory for this to somewhere under /mnt as well, how can I do this in cyanogenmod/Android build system? I tried setting TMP and TEMP but they don't seem to have any effect.

Update: I found a workaround by editing /mnt/android/system/build/tools/releasetools/common.py and setting a temp-dir manually with something like tmpdir = tempfile.mkdtemp(dir='/mnt/tmp') at line 1299, according to documentation mkdtemp should use TMP and TEMP, however that seems to not have worked for me here! Python is at version 2.7.6.
