Thanks, patch applied.

There's one thing I've noticed though: trying to run the 'rebar' binary
doesn't work:

$ LANG=C ./output/host/usr/bin/rebar 
/usr/bin/env: escript: No such file or directory

This is obviously due to:

#!/usr/bin/env escript

at the beginning of the rebar binary, and the fact that
output/host/usr/bin is not in my PATH.
Executing ./output/host/usr/bin/escript ./output/host/usr/bin/rebar
works fine. This is not a problem for Buildroot packages, as
$(HOST_DIR)/usr/bin will be in the PATH. Not sure if it's worth fixing
for other use cases.

Best regards,

Thomas
