commit 68458036c81d141a3899ac4e6ec6ddf0fdfde174
Author: Philip Herron <philip.herron@embecosm.com>

    Disable failing testcase
    
    This commit fed5a41fb1c2c91b77297fdd6d3731078f480441 introduced the concat
    builtin macro but the error handling here is producing an infinite loop
    which was not caught during code-review. This patch disables the offending
    error cases so that it does not impact further development.
    
    Addresses #1102
