[Qemu-devel] [PATCH] Fix configure test for PBKDF2 in nettle

[Steven Luo <steven@steven676.net>]

From: Steven Luo <steven+qemu@steven676.net>

On my Debian jessie system, including nettle/pbkdf2.h does not cause
NULL to be defined, which causes the test to fail to compile.  Include
stddef.h to bring in a definition of NULL.

I suppose this could also be fixed by defining NULL ourselves, or by
replacing NULLs with 0s -- if one of those other approaches is
preferred, let me know.
