lto: no sub-make when --jobserver-auth= is missing

We newly correctly detect that a job server is not active for
a LTO linking:

lto-wrapper: warning: jobserver is not available: '--jobserver-auth=' is not present in 'MAKEFLAGS'

In that situation we should not call make -f abc.mk as it can leed
to N^2 LTRANS units.

gcc/ChangeLog:

* lto-wrapper.c (run_gcc): Do not use sub-make when jobserver is
not detected properly.
