more GNU make 4.2.90 issues on Solaris 10

[Paul Eggert]

After applying the patches I recently sent to bug-make, I still see several 
tests failing on native Solaris 10 sparc (32-bit), built with Solaris tools 
(including Oracle Studio 12.6) instead of with GNU tools. Please see attached 
files, giving the relevant part of the 'make' output and the *.diff files for 
the failing tests.

One problem seems to be that some tests assume that 'make check' runs GNU Make 
instead of /usr/ccs/bin/make, which chatters less.

The work/functions/wildcard test fails because on Solaris 10, the command 
"/bin/sh -c 'kill -2 $$'" causes /bin/sh to call _exit (2000) (!), and the 
kernel discards the high order bits and reports the status 2000 % 256 == 208 to 
the parent process. I suppose one way to work around this is to propagate the 
'SHELL = /bin/bash' line of the top-level Makefile into the little test 
Makefile, since /bin/bash works correctly, but I don't offhand know how to do 
that propagation.

The archives test fails because /usr/ccs/bin/ar is a bit chattier on Solaris.

The vpathplus test fails due to file name order. Perhaps this is because on 
Solaris 10 GNU Make uses its own glob, not Solaris's glob.

I don't offhand see why the output-sync tests are failing.
