Cross compile Agent2 arm: linux/libspechostnamesysinfo.a: No such file or directory

[Luke.01]

I am having troubles to cross compile the agent2 version.

Tried both the package 6.4.13 and the git branch release/6.4.
Compiling on ubuntu 18.04 to arm (source cortexa8hf-neon-poky-linux-gnueabi)

i attached the go env and the 'configure --enable-agent2 --host=arm' summary
the file src/go/Makefile has been modified:
GOOS = `go env GOOS`
GOARCH = `go env GOARCH`
with
GOOS = linux
GOARCH = arm
to avoid the go error goos/goarch pair

but i receive this error

Making all in go

the only thing that i can add is that libspechostnamesysinfo.a and zbxsysinfo/linux/libspecsysinfo.a are in /zbxsysinfo/unknown/

any help?
thank you

i found this temporary solution

modify the configure script:
- host_os=$* -> host_os=linux
- kernel=`uname -r` -> kernel=${KERNEL_VERSION}

where KERNEL_VERSION is host kernel version (4.14 in my case)

and after configure --enable-agent2 --host=arm

i modified the file src/go/Makefile
- GOOS = `go env GOOS` -> GOOS = linux
- GOARCH = `go env GOARCH` -> GOARCH = arm

it hope it can helps
