This asks a question in a different direction that my prior

Background:
/usr/obj/BUILDs/main-amd64-nodbg-clang/usr/main-src/amd64.amd64/tmp/usr/lib/libc++.so:GROUP
( /lib/libc++.so.1 /usr/lib/libcxxrt.so
and:
lrwxr-xr-x 1 root wheel 23 Dec 29 13:17:01 2021 /usr/lib/libcxxrt.so
-> ../../lib/libcxxrt.so.1
Why did libc++.so.1 not get a:
/usr/lib/libc++.so.1 -> ../../lib/libc++.so.1
I forgot to remove the .1 on the left hand side:
/usr/lib/libc++.so -> ../../lib/libc++.so.1
Because for libc++.so we don't just symlink to the current version of the
library
(as we do for most other shared libraries) to tell the compiler what to link
against
for -lc++, instead we use a linker script that tells the compiler to link
against
both of those libraries when -lc++ is encountered.
I have finally reproduced Cy's build error locally and am testing my fix. If it
works I'll commit it.
