a bug that breaks the performance testing mode of the libstdc++ test suite [_two_ dashes before "rpath" where one is the correct # to have]

In fact I agree, but I think we both got confused because the patch, as 
posted, is inverted, is in fact meant to replace -- with -, not the 
other way round ;)

Thus the poster seems right, but we have been using -- for ages and it 
works fine at least on Linux (note, in case isn't obvious to everyone, 
that check-performance isn't really supported for all the targets 
supported by the library in general), thus, in my opinion, before 
changing it we should check again the docs and in case apply the patch 
to mainline only, maybe only 4.8 too.

Paolo.
