[Buildroot] [PATCH] package/libcec: fix missing libraries from rpi-userland

[Yann E. MORIN]

From: "Yann E. MORIN" <yann.morin.1998@free.fr>

When rpi-userland libraries are built as shared-objects, not all needed
libraries are passed in the LD_FLAGS, leading to failure at linkage.

To avoid this issue, set the LIBS variable content in accordance with
INCLUDES variable value.

This is needed because libcec does not use pkg-config to look for the
ldflags needed for -lbcm_host, even though bcm_host provides a .pc
file (even a correct one!)

Hi all,

I could not test if it works or not since I don't have a compatible
hardware, but it builds.
