This is a variant of the wording in bugzilla 220125:
Unless buildworld (not just kernel-toolchain) is used before
buildkernel the result for arm64 is:
--- armv8_crypto_wrap.o ---
In file included from /usr/src/sys/crypto/armv8/armv8_crypto_wrap.c:46:

fatal error: 'stdint.h' file not found

^~~~~~~~~~
--- all_subdir_armv8crypto ---
*** [armv8_crypto_wrap.o] Error code 1
Doing a kernel-toolchain build establishes:

/usr/obj/cortexA53dbg_clang/arm64.aarch64/usr/src/include/xlocale
which excludes the following that a buildworld establishes
(shown from a different build):
# find /usr/obj/cortexA53_clang/ -name stdint.h -print | more
=
/usr/obj/cortexA53_clang/arm64.aarch64/usr/src/tmp/usr/include/sys/stdint.=
h
=
/usr/obj/cortexA53_clang/arm64.aarch64/usr/src/tmp/usr/include/c++/v1/stdi=
nt.h
=
/usr/obj/cortexA53_clang/arm64.aarch64/usr/src/tmp/usr/include/c++/v1/tr1/=
stdint.h
/usr/obj/cortexA53_clang/arm64.aarch64/usr/src/tmp/usr/include/stdint.h
One of:
A) kernel-toolchain needs to establish a stdint.h
that would be found
vs.
B) arm_neon.h needs to avoid needing stdint.h
(presumes armv8_crypto_wrap.c is correct to
include arm_neon.h )
at least if the kernel-toolchain then buildkernel
sequence is to be supported for arm64.
