Thanks, committed. I ended up reworking it to use a simple makefile
instead of scons, both because of the dos/unix newline issue you pointed
out yourself, and also because scons hardcoded compiler flags.

See below for a few other minor issues.

 Frank> +	  multi-format 1D/2D barcode image processing library 

These two lines have trailing spaces.

Buildroot can be used to build a native compiler and development
environment, so we also install into target. If BR2_HAVE_DEVFILES is
disabled, then the target filesystem is cleaned up of usr/lib/lib*.a /
usr/include before the filesystem images are created.
