# Avoid re-computing COMPILER_VERSION, etc. values:
# $CC is different in the libcompat case compared to the non-compat value.
# Since bsd.compiler.mk (and bsd.linker.mk) save the variables using a full
# hash of the compiler/link command, this means that the cached values for
# X_COMPILER_TYPE, etc. cannot be loaded.
# Instead set all the values, so that we can avoid including bsd.compiler.mk and
# bsd.linker.mk. This provides a noticeable speed-up as it avoids multiple
# processes from being spawned in each subdirectory.
