[svn-r11726] Purpose:
Bug fix

Description:
Fixed bug in hl/src Makefile that was deleting y.tab.c.
Running bin/reconfigure changed a few other files as well (somebody
probably updated Makefiles.am but forgot to bin/reconfigure).

Solution:
Automake in its wisdom adds the line "rm *.tab.c" to every distclean
in every directory.  I assume that it assumes that such files are
generated during the build.  Supplied an empty distclean-compile
target to remove this line from the Makefiles.in.

Platforms tested:
mir, sleipnir, shanti
