[dpdk-stable] patch 'mk: fix build of shared library with libbsd' has been queued to LTS release 17.11.7

[Yongseok Koh]

Hi,

FYI, your patch has been queued to LTS release 17.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objection by 07/27/19. So please
shout if anyone has objection.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Thanks.

Yongseok

Subject: [PATCH] mk: fix build of shared library with libbsd

[ upstream commit fdb3798d6f870f79d5fa40b2c3425e8285dd4e44 ]

When building DPDK with "make" and options
	CONFIG_RTE_USE_LIBBSD=y
and
	CONFIG_RTE_BUILD_SHARED_LIB=y
libbsd was not linked, resulting in compilation errors:
	undefined reference to `strlcpy'

The link option -lbsd is added in a common place for both
Linux apps and libs.
It is used in app linkage via EXECENV_LDLIBS,
and in lib linkage via the added variable EXECENV_LDLIBS-y.

Fixes: 5364de644a4b ("eal: support strlcpy function")
