    cpprules.in: squash whitespace in generated files
    
    CPP is used to generate files, but as cpp reads files from the build host the
    output has a number of blank lines at the beginning which varies depending on
    what GCC and friends is used.
    
    Pathalogical example:
    
     $ cpp -undef -traditional /dev/null
     # 1 "/dev/null"
     # 1 "<built-in>"
     # 1 "<command-line>"
     # 31 "<command-line>"
     # 1 "/usr/include/stdc-predef.h" 1 3 4
    
     # 17 "/usr/include/stdc-predef.h" 3 4
    
     [ 40 blank line ]
    
     # 32 "<command-line>" 2
     # 1 "/dev/null"
    
    So depending on the content of stdc-predef.h and what other headers CPP will
    load, the amount of whitespace in the generates files varies. This can result in
    differences in reproducible environments, and file conflicts in multilib
    environments.
    
    As whitespace is irrelevant to these machine-readable files, extend the sed to
    just delete blank lines.
