Why is main's system clang (12.0.1-rc2) using /usr/local/bin/aarch64-unknown-freebsd14.0-ld ? (such breaks things)

Context:

# uname -apKU
FreeBSD CA72_16Gp_ZFS 14.0-CURRENT FreeBSD 14.0-CURRENT #10 main-n247756-348c41d1815d-dirty: Mon Jul  5 10:23:55 PDT 2021     root@CA72_16Gp_ZFS:/usr/obj/BUILDs/main-CA72-nodbg-clang/usr/main-src/arm64.aarch64/sys/GENERIC-NODBG-CA72  arm64 aarch64 1400025 1400025

Note the "/usr/local/bin/aarch64-unknown-freebsd14.0-ld" path
for ld.


I've an example where this usage leads to:

/usr/local/bin/aarch64-unknown-freebsd14.0-ld: /usr/bin/../lib/LLVMgold.so: error loading plugin: Cannot open "/usr/bin/../lib/LLVMgold.so"
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
*** Error code 1
