[Mesa-dev] [PATCH] travis: manually generate sys/syscall.h

[Andres Gomez]

Until now, the needed bits were wrongly included in linux/memfd.h

Since Travis' sys/syscall.h doesn't provide the SYS_memfd_create, we
generate that header manually, including the needed bits to avoid
compilation problems, as the ones observed after:
3228335b55c ("intel: aubinator: handle GGTT mappings")

Fixes: 7e2af374742 ("travis: split the make target to three separate ones")
