[Buildroot] [RFC v1 02/14] package infrastructure: move subdir support to autotools

The <pkg>_SUBDIR variable was currently somewhat handled at the
generic package infrastructure level, with the $(PKG)_SRCDIR variable
taking into account this SUBDIR. But in fact, this <pkg>_SUBDIR
variable only makes sense in the context of the autotools
infrastructure, to indicate that the configure script is not located
at the root of the source tree, but instead in a sub-directory. In the
case of generic packages, the package .mk file already has enough
freedom to handle bizarre situations where the Makefile or other parts
of the build system may not be located at the root of the package
source tree.

In order to simplify the introduction of out of tree support, we
therefore move the SUBDIR support as an autotools infrastructure
specific feature.
