When using a custom GCC stack with binutils included, sometimes CMake will fail to configure the PV*Readers

Many thanks for tagging me on this one... I did have the nagging feeling that there were more places where this might more places where this was needed... but after comparing OpenFOAM-plus with OpenFOAM-dev, I noticed that you had added setting these parameters for the other Allwmake files as well, not done in OpenFOAM-dev, which makes a lot of sense.

But, since now you have this in the child-Allwmake files, does it still need this in applications/utilities/postProcessing/graphics/PVReaders/Allwmake? The vtkPVReaders folder is not relying on CMake, therefore these 2 environment variables for CC and CXX are not needed in this main Allwmake any more.

Hi Bruno, You are right about these lines being redundant in the top-level Allwmake. I debated removing them, but left them for potential extra safety/documentation/etc ... no 100% rational reason.
