# We have the following situation:
# - sysroot directory: $(INSTALL_DIR)/sysroot
# - GCC install directory: $(INSTALL_DIR)
# However, LLVM does not allow to set a GCC install prefix
# (-DGCC_INSTALL_PREFIX) if a sysroot (-DDEFAULT_SYSROOT) is set
# (the GCC install prefix will be ignored silently).
# Without a proper sysroot path feature.h won't be found by clang.
# Without a proper GCC install directory libgcc won't be found.
# As a workaround we have to merge both paths:
