Samuel Martin e8c3755676 pkg-cmake.mk: set CMAKE_SYSROOT variable in toolchainfile.cmake
This change enforces the CMAKE_SYSROOT value set in the toolchainfile.cmake.

This fix overrides the CMake heuristics used to guess it, and turns off some
non-desirable behavior adding "-isystem ..." flags to the compiler command
line, misleading the compiler and making the build failed due to some
unfound standard headers.

# and store it in RELOCATED_HOST_DIR.
# All the other variables that need to refer to HOST_DIR will use the
# RELOCATED_HOST_DIR variable.
