`distclean' incomplete

[Ilya N. Golubev]

Version: 6.3

`make distclean' leaves the following files in build directory.

intl/config.h
intl/config.status
intl/stamp-h
gdb/doc/gdb.info
gdb/doc/gdb.info-1
gdb/doc/gdb.info-2
gdb/doc/gdb.info-3
gdb/doc/gdb.info-4
gdb/observer.h
gdb/ada-lex.c
gdb/observer.inc
utils/sparclite/Makefile
utils/sparclite/config.status
utils/wince/config.status
utils/wince/Makefile

If a new gdb version is configured to build in the same directory, it
may even break the build, in particular, because files left in build
directory are obsolete wrt new version and gdb makefiles in that new
version fail to notice that and rebuild them.
