Support parallel make check with GNU make 4.2+
I noticed that make -jN check would run make check-single when using GNU
make 4.2.1.
In the end, it turned out that this is due to this change from the make
4.2 NEWS file:
* The amount of parallelism can be determined by querying MAKEFLAGS, even when
the job server is enabled (previously MAKEFLAGS would always contain only
"-j", with no number, when job server was enabled).
The fix is trivial: just accept an optional arg to -j in Makefile.in
(saw_dash_j). Tested on i386-pc-solaris2.11 with just make and make
-j/-jN with both make 3.82 and 4.2.1.
* Makefile.in (saw_dash_j): Allow for GNU make 4.2+ passing -jN in
MAKEFLAGS.
