[dpdk-dev] [PATCH v2 1/7] build: always link-whole DPDK static libraries

[Bruce Richardson <bruce.richardson@intel.com>]

To ensure all constructors are included in static build, we need to pass
the --whole-archive flag when linking, which is used with the
"link_whole" meson option. Since we use link_whole for all libs, we no
longer need to track the lib as part of the static dependency, just the
path to the headers for compiling.

After this patch is applied, all DPDK .a files are inside
--whole-archive/--no-whole-archive flags, but external dependencies and
shared libs being linked against remain outside.

V2: amended git log to clarify that external dependencies are unaffected by
this change
