[Buildroot] [PATCH 1/2] package: Add $(HOST_DIR)/usr/lib to LD_LIBRARY_PATH for make & configure env variables

[llandwerlin at gmail.com <llandwerlin@gmail.com>]

From: Lionel Landwerlin <llandwerlin@gmail.com>

Some packages like icu requires to be compiled against the host system
first to be able to compile against the target. This is due to the
usage of self generated binaries by the package to build itself. When
the generated tools also depends on generated libraries it is required
to add the path to these libraries in the library path
(LD_LIBRARY_PATH).
