Set default BUILD_IDLC based on presence of Maven

Browse source 
This will modify the default behavior to select BUILD_IDLC based on
whether Maven is discovered or not.

The behavior when `-DBUILD_IDLC` is specified on the command line remains
unchanged - the build will maintain the current behavior of failing to
configure if `BUILD_IDLC=ON` and Maven was later not found.

This reverts (part of) commit 860a6aadae.
