RE: Allow redefinition of libcilkrts debug macros

[Iyer, Balaji V]

I suspected that much.  It would be good to have a libcilkrts/README.gcc 
describing the rules which changes can go into the gcc tree directly, which 
need to go upstream first, and how.  libo and libsanitizer already have this.

Hi Rainer,
        It is mentioned under the "CONTRIBUTIONS" sections in the 
libcilkrts/README file :).

Thanks,

Balaji V. Iyer.
