Description:
------------
The files removed by vcsclean are only a subset of the files removed by 'make clean'.  File extensions .lo .la .gcno .gcda are not removed by vcsclean.

Using the sequence 'cd php53; svn up; ./vcsclean; ./configure ...;
make' fails to find some .o files.

Some .o's get built but link fails with a bunch of errors of the form:
  gcc: ext/<ext>/.libs/<file>.o: No such file or directory

The vcsclean command removes the ext/*/.libs directories but doesn't
remove ext/*.lo files. This causes C files to be skipped for recompilation and no .libs/*.o files are created. 

A patch is to add .lo to the extension list in build/build.mk.

Also, adding '.la .gcno .gcda' in addition to '.lo' would make
vcsclean consistent with 'make clean'.

A secondary bug is that .o files are not recreated from existing .lo files.
