doc: select_list: parse DEFS from the modules Makefiles
Get all the variable definitions from each module Makefile and
evaluate them to get proper DEFS and INCLUDES (using sed to
extract the variable definitions, conditionals and filter-out
rules from the Makefiles, some hack to preserve the LFs and
$(eval) to evaluate the extracted stuff in the current context).
The DEFS and INCLUDES will be passed to the documentation
generating script (dump_selects.pl) as extra arguments for gcc.
This way the proper defines and includes will be used for each
module.
Fixes select list generation failure for modules with non-standard
include dirs.
