perf jit: Fix build issue on Ubuntu 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.
