Attempting a xtoolchain-gcc head amd64->aarch64 cross buildworld failed for liblto_plugin.so loading error

[Mark Millard]

My attempted, xtoolchain-gcc based, amd64->aarch64 cross-buildworld-buildkernel failed with:

--- libc.so.7.full ---
/usr/local/bin/aarch64-unknown-freebsd12.0-ld: /usr/local/libexec/gcc/aarch64-unknown-freebsd12.0/6.3.0/liblto_plugin.so: error loading plugin: Service unavailable
collect2: error: ld returned 1 exit status
*** [libc.so.7.full] Error code 1

(I've not attempted such a build in a long time, so I do not
know how new this is. Historically I've done lots of such
builds. cortex-a53 was specifically targeted here.)
