debuild/precise-configure.patch

+Fix up LDFLAGS for Precise and earlier (patch by Hans-Christoph Steiner,
+updated to pd-l2ork by Albert Graef).
+Description: fix ./configure dying thinking we're cross-compiling
+ When building using debuild on Debian/squeeze or Ubuntu < quantal,
+ ./configure somehow gets some LDFLAGS for shared libraries and uses them in
+ the gcc tests.  The executable then fails to run since its a shared library,
+ and ./configure thinks we're cross-compiling.  This patch forces no LDFLAGS.
