Compile error:
  CC mlx5.o.pmd.o
mlx5.o.pmd.c:1:227:
error: no newline at end of file [-Werror,-Wnewline-eof]
  ...__attribute__((used)) = "PMD_INFO_STRING= {...}";
                                                      ^

Produced with clang 3.8.0 and MLX5_PMD and MLX5_DEBUG
config options enabled.

Fixes: 98b0fdb0ffc6 ("pmdinfogen: add buildtools and pmdinfogen utility")

What was the error this produced?  It seems like a false positive to me to
require a newline at the end of a string, and it certainly doesn't provide any
benefit when pmdinfo reads it back later.

clang is complaining about missing newline while compiling autogenerated
file, build error is on commit log.
