I can't reproduce this disappearance in a clean up-to-date sid chroot.

AFAICS this is the code responsible for creating /lib/libfoo <-> 
/usr/lib/libfoo symlinks (see include/buildmacros:79):

if [ "x$(shell readlink -f $(PKG_LIB_DIR))" != \
     "x$(shell readlink -f $(PKG_ROOT_LIB_DIR))" ]; then \
        ../$(INSTALL) -S $(PKG_LIB_DIR)/$(LIBNAME).a $(PKG_ROOT_LIB_DIR)/$(LIBNAME).a; \
        ../$(INSTALL) -S $(PKG_LIB_DIR)/$(LIBNAME).la $(PKG_ROOT_LIB_DIR)/$(LIBNAME).la; \
        ../$(INSTALL) -S $(PKG_ROOT_LIB_DIR)/$(LIBNAME).so $(PKG_LIB_DIR)/$(LIBNAME).so; \
fi

I guess the symlinks weren't created on your system only because your 
/lib is symlinked to /usr/lib.
