glibc-testing: Specify location of c++ header files
Glibc test suite contains several c++ files. They are built with g++ -nostdinc. In this case the location of c++ include files needs to be specified explicitly, or the programs may fail to build. The header locations are assumed to be: sysroot/usr/include/c++/<version> sysroot/usr/include/c++/<version>/<machine> The new code parses "configparms" to get the actual CXX and sysroot used for the glibc test suite, then it queries CXX to determine CXX <version> and CXX <machine>. With the known values for <version> and <machine> the code composes a new value for c++-sysincludes and appends "configparms" with that value.
