aarch64 based sysutils/u-boot-rpi[34] (and more?) builds fail for: "aarch64-none-elf-gcc: fatal error: -fuse-linker-plugin, but liblto_plugin.so not found"

[Mark Millard]

The below where based on poudriere-devel based build attempts.
/usr/ports/ was based on head -r532972 and aarch64 FreeBSD was
based on head -r360311 . amd64 FreeBSD did not have the build
problem for the aaarch64-targeted u-boot ports.

The overall build is still going and more aarch64-targeted
u-boot builds might fail.
