After configuring CMakeFiles/CMake<lang>Compiler.cmake in the build tree the second time (to store ABI information), include it immediately. This allows any logic and settings in the compiler information files to be used without duplicating it in CMakeDetermineCompilerABI.cmake. The change in commit "Use Fortran ABI detection results conservatively" (2010-05-05) needs this to use the same logic to set CMAKE_SIZEOF_VOID_P during first and later runs of CMake.
