Other platforms use /usr/lib and /usr/lib64 to support this and
we already detect both:

/usr/lib/jvm/icedtea-7
/usr/lib/jvm/icedtea7
/usr/lib/jvm/java-1.7.0-openjdk
/usr/lib/jvm/java-1.7.0-openjdk.x86_64
/usr/lib64/jvm/java-1.7.0-openjdk

We could try checking for /usr/lib/jvm/java-7-openjdk-${host_cpu} but it
doesn't help that Debian is using a non-standard naming for this (amd64 instead
of x86_64, ppc64el instead of ppc64le)

This is no good. We need specific versions of OpenJDK, not whatever random JVM
the user has selected. Besides, we already have
/etc/alternatives/java_sdk_openjdk as a last resort. Don't tell me, Debian
doesn't provide this either?
