Properly detect working jobserver in gcc driver.
2019-08-02 Martin Liska <mliska@suse.cz>
PR lto/91313
* gcc.c (driver::maybe_run_linker): Call detect_jobserver
to detect working job server.
(driver::detect_jobserver): Test whether jobserver
is active from GCC driver. That will prevent situation where
GCC is invoked from a LD plugin and the linker already uses
file descriptors suggested by make. That leads to a wrong
detection.
* gcc.h (driver): Add detect_jobserver.
* lto-wrapper.c (jobserver_active_p): Simplify sscanf by
not scanning for --jobserver-auth prefix.
