Description of problem:
When using automake to generate a non-recursive Makefile for a package that has
multiple subdirectories, 'make clean' does not delete all generate files.  This
causes 'make distcheck' to fail.  I am attaching a complete example package that
shows this failure; the simple Makefile.am in the top level is:


INCLUDES = -I$(srcdir)/include
AM_CFLAGS = -g -Wall -D_GNU_SOURCE

lib_LTLIBRARIES = src/libbug.la
src_libbug_la_SOURCES = src/bug.c
src_libbug_la_LDFLAGS = -version-info 1 -export-dynamic

bin_PROGRAMS = example/ex
example_ex_SOURCES = example/ex.c
example_ex_LDADD = $(top_builddir)/src/libbug.la

include_HEADERS = include/bug.h

EXTRA_DIST = include/bug.h

if I unpack this package and do

    ./autogen.sh && ./configure && make distcheck

then the build ends with:

 rm -f example/ex example/ex
test -z "src/libbug.la" || rm -f src/libbug.la
rm -f "src/so_locations"
rm -rf .libs _libs
rm -rf src/.libs src/_libs
rm -f *.o
rm -f *.lo
rm -f *.tab.c
test -z "" || rm -f 
rm -f example/.dirstamp
rm -f src/.dirstamp
rm -f config.h stamp-h1
rm -f libtool
rm -f TAGS ID GTAGS GRTAGS GSYMS GPATH tags
rm -f config.status config.cache config.log configure.lineno config.status.lineno
rm -rf ./.deps
rm -f Makefile
ERROR: files left in build directory after distclean:
./example/.libs/ex
make[1]: *** [distcleancheck] Error 1
make[1]: Leaving directory `/users/rdreier/automake-bug/automake-bug-1.0/_build'
make: *** [distcheck] Error 2

and indeed the same thing can be verified with 'make && make clean' -- the
example/.libs directory is not deleted.




Version-Release number of selected component (if applicable):
$ automake --version
automake (GNU automake) 1.10
