--- Comment #19 from Liviu Ionescu <ilg at livius dot net> ---
I'm the maintainer of GNU MCU Eclipse ARM Embedded GCC, a distribution based on
Arm Embedded GCC, and I confirm that I got bitten by this issue too.

FYI, Eclipse uses arm-none-eabi-ar to build static Arm libraries, and when I
tried to use LTO, the result was an error like 'plugin needed to handle lto
object'.

The workaround was to update my distribution build scripts to copy (on Windows)
or link (on Linux and macOS) the LTO plugin to lib/bfd-plugins, a local folder
present in the distribution.

In my oppinion, the LTO plugin should be copied to bfd-plugins by the 'make
install', and not be left at the discretion of the distribution.
