[SPDK] SPDK cross compilation for ARM on x86 host

Hi,

I am trying to cross compile the SPDK for ARM on x86 platform. 
My first question is:
1. Has anyone tried this before or is it supported ?

2. I tried to cross compile SPDK on x86 platform and partially achieved some success. But it seems SPDK does depends on tons of libraries other than DPDK or ISA-L.  These libraries should be already installed in the system and in case if any library has not installed then ./script/pkgdep.sh takes care of that. The issue with pkgdep.sh is, it has no awareness of the cross compilation and resolve the dependency based on native OS/platform. 

2.a:  May anyone suggest a plain list of dependent libraries so that I can manually pull them and cross compile them along with SPDK ?
2.b: Is there anything I can do with pkgdep.sh to make it aware of cross compilation ?
