    devel/orc: work around armv7 libc bug
    
    The armv7 libc has a bug in printf() where printing a denormal double
    may cause NUL bytes to be written out.  This port tries to write a
    diagnostic comment containing such a denormal to a C source file.  The
    bug causes the source file to be malformed, breaking the port and its
    consumers.
    
    Work around the bug by killing the offending part of the diagnostic
    comment.
