How do I cross compile from a Mac to an obscure Linux distribution (embedded)?

I saw this question How to cross compile from Mac OS X to Linux x86? but my target looks like this

$ uname -a
Linux MyDevice 4.9.127-svn20747 #1 SMP Thu Jan 17 05:46:18 UTC 2019 x86_64 GNU/Linux

Some output from less /proc/cpuinfo

processor   : 3
vendor_id   : GenuineIntel
cpu family  : 6
model       : 54
model name  : Intel(R) Atom(TM) CPU D2701   @ 2.13GHz
stepping    : 1
microcode   : 0x10d
cpu MHz     : 2127.900
cache size  : 512 KB

so I doubt there are any readymade solutions.

How do I compile from a Mac to embedded Linux running on an Atom CPU?

This is what I did to compile (Crosscompile? I am not really sure what I did.) bonnie++ on a Mac running VirtualBox with a NAS OS-VM. I think this should apply to most software that one can compile using a simple ./configure; make process.

  1. Download NAS OS SDK VM (NASOS_SDK-0.7.ova) from here https://www.seagate.com/nasos/SDK/0.7/downloads/index.html

  2. Begun following these instructions https://www.seagate.com/nasos/SDK/0.7/multi-arch/index.html¹ until I reached the section Cross Compiling where I was redirected to https://www.seagate.com/nasos/SDK/0.7/cross/index.html.

  3. Skip down to the paragraph that begins with In order to cross-compile our hello program and perform the three exports described there. The TOOLCHAIN_PREFIX can be found in the appropriate directory in /opt: e.g., in the x86_64-seagate-nasos-sdk there is a directory x86_64-seagate-linux-gnu - use that name as the TOOLCHAIN_PREFIX (Why oh why isn't this information included in the guide???).

  4. Perform configure and make as described.

Done.

If someone knows how to perform static linking, please add a comment.

¹ I don't think this is necessary if you try to compile something where ./configure; make already works.

your target is a 64bit x86 platform, which is certainly not obscure. the SO question you linked is the best starting point, spin up a VM of the linux distribution you're targeting on your embedded board, compile in that and scp the executable to the board (or just compile on the board itself, your target is not exactly underpowered)
