Use work-around from bug 4772 for C++ and Fortran

The commit "fix for bug 4772" added a work-around to CMakeCInformation
for platform config files that put compiler information in the system
file (like SunOS flags for GCC).  This commit adds the same work-around
for CXX and Fortran.  It is necessary to support enabling these
languages separately from C in other subdirectories.

The commit "Avoid (Unix|Windows)Paths.cmake multiple include" added
include blockers that prevent the files from multiple inclusion, so it
is safe to include the system information files from every language.

See issue #4772 and issue #9656.
