Conversion of BSP config files to pkg-config files

[Vijay Kumar Banerjee]

Hello,

I want to work on the ticket #3302 <https://devel.rtems.org/ticket/3302> as a
summer project.

The goal of the project is to convert the BSP cfg files from `make` format to the
pkg-config (.pc) format. The approach would be to first make all the flags and
Makefile macros used in the bsp .cfg files, consistent. Since the problem is
complex and a huge number of files are there to deal with, I'll first manually
look into a few bsps and then move forward to write a parser in python
to parse and compare the .cfg files of different BSPs. Once we get a consistent
format for the .cfg files, we'll move on to generate the .pc files for the bsps.

I seek some guidance and discussion on the project to get started with it.

Thanks
