The makefile setup you've created has a fatal flaw; it completely
blows up if you are building with VPATH.  That is, try this with your
patch: (starting with cwd in the e2fsprogs source tree)

% mkdir build
% cd build
% ../configure
% make
% make check
    <boom>

Could you take a look at fixing this, please?  I rely pretty
exclusively on building with VPATH (that way I can have a
build.static, build.32, etc.) with a single source tree.
