On larger parallel WHOPR builds I find it useful to see in top which
phase a given lto1 is in.

Set the process name to lto1-wpa, lto1-ltrans, lto1-lto depending
on the current mode.

This is currently only implemented for Linux and only
using the "comm" process name, which is reported in top.

v2: Moved function to libiberty, renamed setproctitle to match
BSD. In theory it should pick up BSD's libc function for this
on a BSD system, but I haven't tested this.

-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?
