[dpdk-dev] [PATCH] eal/linux: fix build with glibc 2.25

[Jerin Jacob]

glibc 2.25 is warning about if applications depend on
sys/types.h for makedev macro, it expects to be included
from <sys/sysmacros.h>

Found this error while testing with GCC 6.3.1 on archlinux.

lib/librte_eal/linuxapp/eal/eal_pci_uio.c: In function ‘pci_mknod_uio_dev’:
lib/librte_eal/linuxapp/eal/eal_pci_uio.c:134:13:
error: In the GNU C Library, "makedev" is defined
by <sys/sysmacros.h>. For historical compatibility, it is
currently defined by <sys/types.h> as well, but we plan to
remove this soon. To use "makedev", include <sys/sysmacros.h>
directly. If you did not intend to use a system-defined macro
"makedev", you should undefine it after including <sys/types.h>. [-Werror]
 dev = makedev(major, minor);
