[Buildroot] [PATCH 1/1] busybox: add conditional dependency on libselinux (v2)

[Chris Stone]

If you select the selinux applets when configuring
busybox then the busybox build fails due to a missing selinux.h file. This is
because there is no dependency on libselinux in the busybox make. The lack of
dependency is completely understandable, since there is no such dependency
when a user does not configure in the selinux applets. The attached patch
adds a conditional libselinux dependency to the busybox make when the
libselinux package has been selected for the target. It is not unreasonable
to assume that if a user selects libselinux, then he may also select the
busybox selinux applets. Additionally, if the user has already selected
libselinux for the target, then adding a dependency to libselinx to busybox
does no harm, even if the user does not configure in the selinux applet.
