too slowly and can't finish compiling project for arm target by using qemu in x86 ubuntu

[xmuchen]

I need to cross-compile project for nvidia jetpack, by using qemu tools to build arm target on x86 host.But compiling is too slowly and couldn't finish which always block after a few minutes.Do you compile successfully on that case?If yes, How fast for compiling it,and giving some suggestions to improve speed, thanks a lot.
