Upstream-Status: Pending

# by default c++ include directories are not relative to "--sysroot"
# which brings one trouble when using the toolchain in an environment
# where the build directory generating that toolchain doesn't exist,
# e.g. in sstate, machine specific sysroot and relocatable SDK
# toolchain. This patch now enables c++ include paths under sysroot.
# This way it's enough as long as "--sysroot" is correctly enabled
# in the new environment.
