Thinlto build is requested, but the C++ toolchain doesn't define an action_config for 'lto-backend' action #423
Description
After updating from v1.22.1 to v1.23.0, my release builds started failing with the error:
Thinlto build is requested, but the C++ toolchain doesn't define an action_config for 'lto-backend' action
My .bazelrc contains the following lines:
# sanitizers enabled by default
common --features=asan --features=ubsan
# no sanitizers in release build, but enable Thin LTO
common:release --features=-asan --features=-ubsan --compilation_mode=opt --features=thin_lto
There was no error in v1.22.1, although I see that -flto=thin was applied just to my targets where I explicitly set the flag, so apparently --features=thin_lto was not supported before.
