benchtests: Building benchmarks as static executables

Building benchmarks as static executables:
=========================================

To build benchmarks as static executables, on the build system, run:

  $ make STATIC-BENCHTESTS=yes bench-build

You can copy benchmark executables to another machine and run them
without copying the source nor build directories.
