[dpdk-stable] [PATCH 7/7] Regenerate meson.build changes required due to reverts

[Christian Ehrhardt <christian.ehrhardt@canonical.com>]

Due to a series of re-re-reverts by this case:
http://mails.dpdk.org/archives/stable/2021-March/029418.html
http://mails.dpdk.org/archives/stable/2020-September/024796.html
The two changes of:
  3f33f5056 build: fix plugin load on static build
  4a2baf099 build: fix linker flags on Windows
would have been lost.
Re-apply them here to have the reverts only remove what was added by them.

Fixes: 16ade738fd0d ("app/testpmd: build with meson")
Fixes: 89f0711f9ddf ("examples: build some samples with meson")
Fixes: b031e13d7f0d ("build: fix plugin load on static build")
