I updated lang/gcc9 port to include changes required to enable gccjit,
so instead of GCC trunk, I ended up using GCC 9.3.0

The port takes care of using ld from binutils.

my configure flags were same as mentioned previously, and gmake switches
are:
gmake BYTE_COMPILE_EXTRA_FLAGS='--eval "(setq comp-speed 0)"'
I guess I can try with NATIVE_FAST_BOOT=1 V=1. I will report back.

I used the FreeBSD ports to install everything. Whereas you used GCC
from trunk unlike me, and used these GNU make arguments, which I wasn't.
Anyways, I'll report back with my results.
Thanks!
