Bug 234784: graphics/gdk-pixbuf2: Does not build with only one make job
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=234784



--- Description ---
Now here's an interesting one.

I can reproduce the build error quoted by gergely.czuczy at harmless.hu in bug
#231969 under the following circumstances:

Host: 12.0 amd64
Build jail: 12.0 i386

gdk-pixbuf2 reproducibly fails to build with

...
generated_.._resources.c.o' -MF
'tests/tests@@cve-2015-4491 at exe/meson-generated_.._resources.c.o.d' -o
'tests/tests@@cve-2015-4491 at exe/meson-generated_.._resources.c.o' -c
tests/resources.c
cc: error: no such file or directory: 'tests/resources.c'
cc: error: no input files
ninja: build stopped: subcommand failed.
*** Error code 1

if it is restricted to a single make job.
I *have* to set ALLOW_MAKE_JOBS_PACKAGES="gdk-pixbuf2" in poudriere.conf to
obtain a successful bulk build.

To confirm, "poudriere testport" builds fail reproducibly if adding
MAKE_JOBS_UNSAFE=yes in gdk-pixbuf2's port Makefile.
