(In reply to Lorenzo Salvadore from comment #19)

My comment #17 is related to what I'd referenced in #2, for sure.
I should have referenced #2 explicitly.

Agreed that there is no need to revert to gcc11: it has the
same issue since the problem with /lib/libgcc_s.so.1 use is
on the FreeBSD side of things for aarch64, FreeBSD not matching
what gcc has long defined as needed for the likes of libstdc++
use for aarch64. The mismatch for a tier 1 context is
unfortunate in my view.

Agreed that the addition of the likes of:

EXTRA_LDFLAGS+= -Wl,-rpath=${LOCALBASE}/lib/gcc${GCC_DEFAULT}

is an additional change. (The specifics would not automatically
track potential future USE_GCC= use from what I can tell. I'm
not aware of a technique to get general automatic rpath tracking.
I had hoped someone would know a way to do so. Otherwise the
Makefile content is easy to end up mismatched. This applies to
more than EDK2.)

I'll need to synchronize my ports environment to have a context
to deal with setting up a tested patch based on GCC_DEFAULT. So
it may be a while.
