[petsc-dev] Intel compilers + CUDA

--compiler-bindir <directory>               (-ccbin)                          
        Specify the directory in which the compiler executable (Microsoft 
        Visual Studion cl, or a gcc derivative) resides. By default, this 
        executable is expected in the current executable search path.

It says it will look for the default compiler in the specified path -
and doesn't mention that it can switch the compiler. Ah - the manpage
is misleading.. Looks like '--ccbin icc' works..

So '--with-cc=icc' --with-nvcc='nvcc --ccbin icc' should work.. Will check..
