--- Description ---
Scenario:
- using qemu-user-static to cross compile ports in FreeBSD 13 armv6
- The native boot shows (in dmesg.boot)

FreeBSD 13.0-CURRENT #0 r361029M: Fri May 15 16:26:48 CEST 2020
    root@v903.xyzzy:/auto/z/OBJ/FreeBSD/amd64/head/arm.armv6/sys/RPI-B arm
FreeBSD clang version 10.0.0 (git@github.com:llvm/llvm-project.git
llvmorg-10.0.0-0-gd32170dbd5b)

- But here, qemu-user-static is used instead, chrooting to the armv6
installation.
- The amd64 host is also at r361029.

Result:
- There are many lines of

qemu: unsupported syscall: 574 (calling anyway)
qemu: unsupported syscall: 574 (calling anyway)=20=09=09=09=20=20=20=20=20=
=20=20

qemu: unsupported syscall: 574 (calling anyway)
qemu: unsupported syscall: 574 (calling anyway)

- These lines sometimes even confuse tools, causing the build to fail.

Could you please add the latest syscalls to this port?
