Compiling with LTO when I got
plugin needed to handle lto object
It appears the liblto_plugin.so is in /usr/lib/bfd-plugins instead of /usr/local/lib/bfd-plugins
I can soft link to bypass, but it should be fixed.
$ sudo mkdir /usr/local/lib/bfd-plugins
$ sudo ln -s /tmp/tcloop/gcc/usr/local/libexec/gcc/aarch64-unknown-linux-gnu/10.2.0/liblto_plugin.so.0.0.0 /usr/local/lib/bfd-plugins/liblto_plugin.so
