[dpdk-dev] [PATCH] doc: add note on build issues with gcc < 5.0

[Pablo de Lara]

The following crypto PMDs use the Intel Multi-buffer library:
- AESNI MB PMD
- AESNI GCM PMD
- ZUC PMD
- KASUMI PMD
- SNOW3G PMD

When this library is built with gcc < 5.0, it might throw
some compilation issues. A workaround has been added in the
repo of this library, so a note on this has been added
to the documentation of these PMDs.
