arm-none-eabi-g++ error fuse-linker-plugin, but liblto_plugin.so not found

[reneman]

I move my embedded toolchain for C++ SAMD21 from Ubuntu 16 to Ubuntu 20.4 and arm-none-eabi-g++ no longer compiles my project. This is the error I get:

arm-none-eabi-g++: fatal error: -fuse-linker-plugin, but liblto_plugin.so not found
compilation terminated.

Seems like liblto_plugin is either not installed, or installed but not found. What is this library and how could I solve this issue?

My makefile runs this:

If i were you i'd probably grab the install package once again , and do a new install

The 2017-q4 is a bit down on the page

This worked like a charm. I had previously copied the same .so file from a previous (4.X) gcc version and it already worked and built just fine, but using 2017-q4, the same toolchain version, seems like a better idea and works equally well. So yeah, just copy the missing file(s) and the build process worked again
