Illegal instruction on new port mongodb49 on arm64

Hi,

I created a new port for mongodb49: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=254631
It compiles fine: https://www.klop.ws/mongodb49-4.9.0.r0.log

When I run an application I get "Illegal Instruction" error.

==============================================================

NB: The default of the port uses LTO. I disabled it on my build system because of lack of memory.

Can anybody help me with this?

It would be interesting to know if this also happens on amd64.

Regards,
Ronald.
