m4_ax_boost_base.m4 unnecessary?
We currently have two tests for boost_base:
- dune-common/m4/ax_boost_base.m4 and
- dune-fufem/m4/m4_ax_boost_base.m4.
The only difference that I can spot is this: To the dune-common version, the following change has been applied:

[m4] Don't let the boost magic leak temporary LDFLAGS [[Imported from SVN: r6448]]
which has it use namespaced variables like ax_boost_base_save_CPPFLAGS rather than CPPFLAGS_SAVED="$CPPFLAGS". So my question is: Do we really need another copy in fufem?
