[v3,0/5] improve building examples

  This patchset adds support for testing a number of examples using the
DPDK pkgconfig file, allowing us to check that the file works. It also
includes some more general cleanups for the examples, including adding
support for building from pkg-config to a couple of examples which were
missing that.

V3:
 * fix missing -DUSE_EXPERIMENTAL_API cflag when building using "make
   examples"

V2:
 * separated out a few bug-fixes into a separate set from this one
 * changed to use --define-prefix flag for pkgconfig rather than a
   custom environment variable.


Bruce Richardson (5):
  examples: add support for relocated DPDK install
  devtools/test-meson-builds: remove dependency on clang
  devtools/test-meson-builds: add testing of pkg-config file
  examples/vdpa: support building from pkg-config info
  examples/vhost_crypto: support building from pkg-config info
