Debugging info missing in some packages

I've come across a few RPMS with missing debuginfo and wasted a great
deal of time trying to rebuild to get the debuginfo.

The problem seems to be that some ant scripts force debugging to be
off or perhaps inherited from a property that no-one remembered to
set.  This is compounded by the fact that some ant scripts unzip source
archives and then call ant recursively to build them: in such a case
it's very hard to patch build.xml to force debugging=true.

This patch for ecj forces debuginfo always to be generated while
rebuilding an RPM, no matter what ant thinks.  I realize it's
something of a kludge, but it's better than the current situation.

When compiling C/C++/etc, RPM passes "-g" in RPM_OPT_FLAGS.  An
alternative to this patch might be to scan RPM_OPT_FLAGS for "-g" and
only turn on debugging if it's present.  However, I doubt that in
practice it'd make any difference.

Andrew.
