multicore-linux-x86_64 should alias to multicore-linux64
If you try to build with linux-x86_64 instead of linux64 our build script aborts with the following error:
$ ./build AMPI multicore-linux-x86_64 -j16 --with-production -g Error> option: linux is not supported in this version! Supported compilers: clang craycc gcc icc icc8 iccstatic pgcc xlc xlc64 Supported options: bigemulator bigsim g95 gfortran ifort lcs omp ooc papi persistent pgf90 tsan
multicore-win64 and mpi-win64 should also have aliases, since we now have netlrts-win-x86_64.
