[Buildroot] [PATCH v10 5/6] package/pkg-autotools.mk: Add PKG_GIR_EXTRA_LIBS_PATH variable

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

From: Adam Duskett <Aduskett@gmail.com>

Some packages require passing an extra libs path to gobject-introspection
in order to compile their respective typelib files. This allows users to
specify a PKG_GIR_EXTRA_LIBS_PATH variable in the respective packages mk file
that will then be passed on to the g-ir-scanner, allowing those directory paths
to be indexed.
