    lto: support --jobserver-style=fifo for recent GNU make

    gcc/ChangeLog:

            * opts-jobserver.h: Add one member.
            * opts-common.cc (jobserver_info::jobserver_info): Parse FIFO
            format of --jobserver-auth.

 gcc/opts-common.cc   | 17 +++++++++++++++--
 gcc/opts-jobserver.h |  2 ++
 2 files changed, 17 insertions(+), 2 deletions(-)

Which makes some sense as I locally run GNU make with --shuffle enabled by
default: https://savannah.gnu.org/bugs/index.php?62100

It should generate environment something like 'MAKEFLAGS= -j2
--jobserver-auth=3,4 --shuffle=1660054175'.
