[Buildroot] RFC: option to Makefile.autotools.in to build in $(PROJECT_BUILD_DIR)

I've got a package which will use Makefile.autotools.in that needs to
build in $(PROJECT_BUILD_DIR), because it builds kernel modules.

Here is my proposed patch to Makefile.autotools.in to support this (via
a FOO_BUILD_PROJECT_DIR = YES/NO option). Feedback welcome; unless
there's issues I will commit in a day or two.
