Attempts to build ndctl in an epel-6 environment fail with the following
messages:
In file included from util/filter.c:24:
./daxctl/libdaxctl.h:22: error: redefinition of typedef 'uuid_t'
./ndctl/libndctl.h:26: note: previous declaration of 'uuid_t' was here
Newer compilers discard the error since it sees the types are
compatible, but the definition should be coming from uuid.h when built
with libuuid. Arrange for an AC_DEFINE for the HAVE_UUID symbol when
libuuid is detected by PKG_CHECK_MODULES.
