[Greg Chicares]

branch: master
commit 7a434503255a3435f51dd6b4e649edc20815b641
Author: Gregory W. Chicares <gchicares@sbcglobal.net>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Don't attempt to build "erroneous" targets
    
    This command:
    
      make \
        LMI_COMPILER=gcc \
        LMI_TRIPLET=x86_64-pc-linux-gnu \
        USE_SO_ATTRIBUTES=1 \
        check_concinnity
    
    no longer attempts to compile anything; instead, it emits:
    
      *** in context, cannot build "test_coding_rules".  Stop.
    
    Retained a somewhat similar test in 'GNUmakefile', because it gives
    a more informative error message.
