From: Anton Blanchard <an...@samba.org>
When building on Ubuntu 16.04, I get the following error:
Makefile:49: *** the openjdk development package appears to me missing, install
and try again. Stop.
The problem is that update-java-alternatives has multiple spaces between
fields, and cut treats each space as a new delimiter:
java-1.8.0-openjdk-ppc64el 1081
/usr/lib/jvm/java-1.8.0-openjdk-ppc64el
Fix this by using awk, which handles this fine.
