spec2006 fp test failed with 416.gamess and 481.wrf

when i ran with `--benchmark_subset=fp --benchmarks=speccpu2006` and use "linux64-x64-gcc47.cfg" file according to https://github.com/GoogleCloudPlatform/PerfKitBenchmarker/issues/156
it's ok with int test, but when ran fp test, i got errors as follows
