[i-g-t] pull in headers for major/minor/makedev funcs

Commit Message

Mike Frysinger June 22, 2016, 11:08 a.m. UTC

Use the portable autoconf helper to figure out which header to include
for these funcs.  Linux C libs are moving to not implicitly include them
via sys/types.h anymore, and other OS's have long required you to pull
in the right header directly.
