I checked, issue is new, it's a gcc 5 regression.

Huh, can you reproduce that with an installed compiler?  It seems to simply
build a single source file with -flto.  Maybe it's some issue with dir
separators
in lto-wrapper or the linker plugin?  Does it reproduce with
-f[no-]linker-plugin
or without -flto-partition=none?

I guess it's related to PR65582. So we first have to sort out the mingw-w64
issue.
