gcc-runtime-related fixes

It's useful to know what the various libraries are that get produced by gcc-runtime, as well as to have a specific SUMMARY for the recipe.

In order to use certain features of gcc, you need the corresponding runtime library. It seems to me that these ought to be installed by default when installing the compiler since they are required if certain command line options are used, so add them to RRECOMMENDS. I used RRECOMMENDS since some of these packages may or may not exist depending on architecture and build options; additionally it makes it possible to use BAD_RECOMMENDATIONS if you really want to exclude them.

The impact of this isn't too bad in the context of an image providing on-target compilation - about a 30MB increase in size for an image containing gcc and g++.

My aim was to give some explanation as to why these things might be installed if a user was to find them in their image. Are these libraries used by other compilers?

Cheers,
Paul

yes, clang can use the gcc runtime, I am sure
intel compiler can use it on linux as well and so
will others who target linux

If you build an app with clang and include it in your image, are there not any clang-specific runtime files that are required to additionally be added to the image so the clang-compiled binaries can run?
