[PATCH 4/4] eglibc: Fixes for running regression tests

[Khem Raj <raj.khem@gmail.com>]

Override cxx-sysincludes along with CC and CXX
since it contains path pointing to tcbootstrap
sysroot which does not have c++ headers and libraries

Drop shorten-build-commands patch since it
did not override the include flags for c++ headers
when tests written in c++ are executed the @includes file
does not get updated to add c++ header paths
This patch only reduced the build output anyway

Add a patch to point eglibc to look into c++
headers the way OE installs them its not standard
install e.g. usr/include/c++/GCC_VER but instead
usr/include/c++. This lets g++ find the headers
in right place when compiling c++ testcases

-This patch scratches an itch.  Each individual gcc command in the
-glibc build is over 1K, which means it takes up a good chunk of my
-terminal.  Most of that is include paths.  Any version of GCC new
-enough to build glibc supports response files, which were added in
-2005.  So use a response file for the static list of include paths.
-Now the build commands are a lot shorter, and easier to use when
-developing glibc.
-
-Tested on x86_64-linux-gnu.  Please apply if acceptable.
