Re: New kernel-toolchain buildkernel problem for amd64 -> aarch64 cross build ( after -r336348 ) : ld used for addf_data only can target: elf_x86_64_fbsd elf_i386_fbsd

Result is unchanged. Details follow.

With:

# svnlite diff /usr/src/Makefile.inc1

used via:

# ~/sys_build_scripts.amd64-host/make_cortexA53_nodebug_clang_bootstrap-amd64-host.sh -j4 kernel-toolchain buildkernel

I still get:

--- buildkernel ---
Building /usr/obj/cortexA53_clang/arm64.aarch64/usr/src/arm64.aarch64/sys/GENERIC-NODBG/modules/usr/src/sys/modules/accf_data/accf_data.kld

ld: unrecognised emulation mode: aarch64elf
Supported emulations: elf_x86_64_fbsd elf_i386_fbsd
*** [accf_data.kld] Error code 1



Reminder of what my .sh script does:

# more ~/sys_build_scripts.amd64-host/make_cortexA53_nodebug_clang_bootstrap-amd64-host.sh
kldload -n filemon && \
script ~/sys_typescripts/typescript_make_cortexA53_nodebug_clang_bootstrap-amd64-host-$(date +%Y-%m-%d:%H:%M:%S) \
env __MAKE_CONF="/root/src.configs/make.conf" SRCCONF="/dev/null" SRC_ENV_CONF="/root/src.configs/src.conf.cortexA53-clang-bootstrap.amd64-host" \
WITH_META_MODE=yes \
MAKEOBJDIRPREFIX="/usr/obj/cortexA53_clang/arm64.aarch64" \
make $*

(I'll not repeat the other supporting material.)
