Fabrice Fontaine 2c2c0192a2 package/pkg-cmake.mk: don't unconditionally set CMAKE_CXX_COMPILER
Don't unconditionally set CMAKE_CXX_COMPILER as it will raise a build
failure on qpid-proton because "if the toolchain specifies a value for
CMAKE_CXX_COMPILER, then CMake assumes the compiler works and goes
straight ahead trying to use it":

# RELOCATED_HOST_DIR variable.
