Hi,

recent 14.0-ALPHA1 sources is giving an error:

Building /usr/obj/usr/src/arm64.aarch64/obj-lib32/lib/libssp_nonshared/libssp_nonshared.o
Building /usr/obj/usr/src/arm64.aarch64/obj-lib32/lib/libgcc_eh/int_util.o
error: unable to create target: 'No available targets are compatible with triple "armv7-unknown-freebsd14.0-gnueabihf"'
1 error generated.
error: unable to create target: 'No available targets are compatible with triple "armv7-unknown-freebsd14.0-gnueabihf"'
*** [libssp_nonshared.o] Error code 1

Commandline:
make -j`sysctl -n hw.ncpu` WITH_META_MODE=1 TARGET=arm64 TARGET_ARCH=aarch64 buildworld buildkernel

The build runs in clean objdir, src git hash 220427da0e9b2c1d8e964120becc17eb7524e46f

Host runs 14.0-CURRENT 28d2e3b5dedf

Am I missing something obvious?
Thanks.
