Subject: [PATCH] [ng] clean: simplify cleaning of compiled objects

* automake.in (handle_compile): Compiled objects are always to be
removed upon "make mostlyclean", never requiring a much stronger
"make distclean" to be cleaned.  Simplify accordingly.
* am/compile.am: Simplify accordingly, and do not bother cleaning
'*.tab.c' files, that shouldn't be left behind by Automake-generated
Makefiles anyway.
