It does, cleanly. Output is (for v5.1-rc4):

./usr/include/asm-generic/fcntl.h:119: leaks CONFIG_64BIT to userspace where it is not valid
./usr/include/asm-generic/mman-common.h:22: leaks CONFIG_MMAP_ALLOW_UNINITIALIZED to userspace where it is not valid
./usr/include/linux/elfcore.h:62: leaks CONFIG_BINFMT_ELF_FDPIC to userspace where it is not valid
./usr/include/linux/flat.h:17: leaks CONFIG_BINFMT_SHARED_FLAT to userspace where it is not valid
./usr/include/linux/atmdev.h:104: leaks CONFIG_COMPAT to userspace where it is not valid
./usr/include/linux/pktcdvd.h:37: leaks CONFIG_CDROM_PKTCDVD_WCACHE to userspace where it is not valid
./usr/include/linux/raw.h:17: leaks CONFIG_MAX_RAW_DEVS to userspace where it is not valid
./usr/include/linux/hw_breakpoint.h:27: leaks CONFIG_HAVE_MIXED_BREAKPOINTS_REGS to userspace where it is not valid
./usr/include/linux/eventpoll.h:82: leaks CONFIG_PM_SLEEP to userspace where it is not valid
./usr/include/asm/auxvec.h:14: leaks CONFIG_IA32_EMULATION to userspace where it is not valid
./usr/include/asm/mman.h:7: leaks CONFIG_X86_INTEL_MEMORY_PROTECTION_KEYS to userspace where it is not valid

Which suggests it might be doable to silence these warnings.
