This was due to a misconception om my part where I believed that if one wrote --with-jvm-variants=server one got a C2 compiler and --with-jvm-variants=client one got a C1 compiler and --with-jvm-variants=tiered one got a tiered C1/C2 compiler. Sadly, this is not the case. The following patch reverts the default.
