12# directory to avoid any ABI issues that might cause the built binary to crash.
13# The only exceptions to this are sys/cddl/compat for dtrace bootstrap tools and
14# sys/crypto for libmd bootstrap.
15# We have to skip this check during make obj since bsd.crunchgen.mk will run
16# make obj on every directory during the build-tools phase.
