So, why would my rustc have a different cfg-output? I have it built with the
following options:

# Options for rust-1.22.1_2
_OPTIONS_READ=rust-1.22.1_2
_FILE_COMPLETE_OPTIONS_LIST=DOCS GDB LLNEXTGEN SOURCES
OPTIONS_FILE_UNSET+=DOCS
OPTIONS_FILE_UNSET+=GDB
OPTIONS_FILE_SET+=LLNEXTGEN
OPTIONS_FILE_UNSET+=SOURCES

The CPUs in this machine are old -- could it be, it does not find SSE3 (or some
other later addition) and presumes, SSE2 is not there either?
