I just had a quick look. The only "bug" that forbids you to build in a 
separate directory is the usage of $(top_srcdir) in example_c/Makefile.am

Just replace

cross_CFLAGS = -I$(top_srcdir)/../include

by

cross_CFLAGS = -I$(top_srcdir)/include

and everything is fine !

To make this change permanent, you can create a patch, put it in your 
package set in a patches/ subdirectory and add

   patches: 
$AUTOPROJ_SOURCE_DIR/patches/001_lwpr_fix_build_in_builddir.patch

to the corresponding entry in the source.yml's version_control: section.

Always remember that you must NOT delete a patch file from the package 
set once it is there, or it will break the unpatching/patching process 
for your users.
