Mark linker Makefile rules for job server build

-fwhopr=jobserver requires telling GNU make that the linker (= lto)
rules support job server, so that the necessary jobserver
information is passed through.

Add + to all the executable targets that run LTO for this purpose.

This improves build performance with a -fwhopr=jobserver
bootstrap (or BUILD_CONFIG=bootstrap-lto) significantly.

I didn't change Ada because that apparently doesn't support LTO.

Passes bootstrap and test suite. Ok to commit?
