Mark Johnston 8e1a7e29b6 sanitizers: Avoid building genassym.c and genoffset.c with sanitizers
Some, particularly KASAN, may insert redzones around global symbols,
resulting in incorrect offset definitions because genassym.sh (ab)uses
symbol sizes to assign semantic meaning.

(Ideally I would be able to define this pattern in one place, but I
haven't found a way to define a GENSYM_CFLAGS that actually works for
all of the consumers (kern.post.mk, kmod.mk, sys/conf/files*).)

# +++ variables +++
#
# CLEANFILES Additional files to remove for the clean and cleandir targets.
#
# EXPORT_SYMS A list of symbols that should be exported from the module,
# or the name of a file containing a list of symbols, or YES
# to export all symbols. If not defined, no symbols are
# exported.
#
# KMOD The name of the kernel module to build.
#
# KMODDIR Base path for kernel modules (see kld(4)). [/boot/kernel]

#
# KERNBUILDDIR Set to the location of the kernel build directory where
# the opt_*.h files, .o's and kernel winds up.
#
# BLOB_OBJS Prebuilt binary blobs .o's from the src tree to be linked into
# the module. These are precious and not removed in make clean.

# unload:
# Unload a module.
