Illegal instruction on new port mongodb49 on arm64

[Ronald Klop]

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.
