bootcode.bin is only likely to help stages before
u-boot.bin starts. If it makes to to u-boot.bin
starting, bootcode.bin is then likely irrelevant
from then on.

In fact bootcoce.bin is what loads the start*.elf
that is used. If the start*.elf starts, bootcode.bin
is likely irrelevant past that point.

[The purpose of bootcode.bin is the special boot mode,
more recent versions having more adjustments. There is
no special version of bootcode.bin that I'm aware of.]

Was this based on mina ports before vs. after:

sysutils/edk2: Fix build on aarch64
Build on aarch64 was failing with the following error:

ld-elf.so.1: /lib/libgcc_s.so.1: version GCC_4.5.0 required by
/usr/local/lib/gcc11/libstdc++.so.6 not found

Fix by using /usr/local/lib/gcc*/libgcc_s.so.1 instead.

While here, also define WWW variable.

I'll note that quarterly did not get the update yet.

shows sysutils/edk2@rpi4 as having successfully built:

(So built under 13.1-RELEASE.)

It also shows sysutils/edk2@fvp has having built just
fine.

@rpi3 and the default build have not started building
yet. 4 flavors (bhve, xen, and 2 qemu variants) are
amd64 only and so are ignored.

(sysutils/uefi-edk2-bhyve-csm is something separate.)
