If libunwind is added to the build system samba package can be build using libunwind as a dependency. This is not declared in the samba recipe.


Manual Workaround:

1. make libunwind 
2. make samba

On the recipe:
1. Modify Samba bb recipe as follows:
PACKAGECONFIG[libunwind] = "--with-libunwind,--without-libunwind,libunwind"

2. make samba

Steps to Reproduce

To re-create the issue you can follow these steps:
1. Build an image which contains libunwind and Samba packages
2. make libunwind.distclean
3. Comment out the #ifdef around the inclusion of libunwind.h in source3/lib/util.c as follows
/* #ifdef HAVE_LIBUNWIND_H */ 
#include <libunwind.h> 
/* #endif */ 

4. make samba.rebuild
