    tools/bc: remove useless patch
    
    The remaining changes in this patch to the configure script
    has no effect at all since autoreconf is used with bc
    and the recent update to bc removed the need to patch
    the original set of changes in order to fix building.
    
    Remove the patch.
    
    Removed:
     - 002-fix-libmath.patch
    
    Fixes: abd424c3e ("tools/bc: update to 1.08.1")
