Hi!
As mentioned in the PR, older binutils (like 2.25) complain on these tests
when using -r that:
plugin needed to handle lto object
The following patch introduces an effective target and guards those tests on
a linker with this issue fixed.
Regtested on x86_64-linux and i686-linux, plus regtested on x86_64-linux
with 2.25 binutils, where the patch converts all those FAILs into
UNSUPPORTEDs.
Ok for trunk?
