dts problem during compile from source on aarch64

Today I try to compile the freebsd source code on a vm started by qemu.
I use the same method as I compile it on my x86_64vm, that is
make buildkernel -j8

It seems(means I'm not sure) compiled successfully but problems comes out when linking.

I pasted a 4-thread compile log below, hope to provide some info

sh: /root/zswap4BSD/sys/tools/fdt/make_dtbo.sh: Permission denied
but there is no permission denied, I'm using root.

and I run this script straightly

# sh /root/zswap4BSD/sys/tools/fdt/make_dtbo.sh
No DTS overlays specified


I guess I should do some configure to specified the "DTS overlay", but I don't know what can I do even unable to find the manual.

or should I do something in qemu?
 
I checked this sh, and found the dtso files shoud be under path sys/dts/{myarch}/overlays, and the makefile in this path

Code: 
DTSO!=ls ${.CURDIR}/*.dtso

all: test-dtso

shows some filename shoule be passed to ${DTSO}

and in the Makefile.inc under dts , it called the shell script mentioned above
Code: 
test-dtso:
.for dtso in ${DTSO}
    @env MACHINE=`basename ${.CURDIR}` ${SYSDIR}/tools/fdt/make_dtbo.sh ${SYSDIR} ${dtso} /tmp
.endfor

I think maybe I have done something wrong when specific the arch?
I will continue to find the problem.
 
o_O I solved this problem.

Just because some files were broken. I re-download the source, and then solved.
