[patch] libjava: avoid using escape sequence with undefined behaviour in echo

[Matthias Klose]

When using ash as system and config shell, the bootstrap fails in libjava,
because a wrong Makefile.deps is generated. echo '\1\2' in ash just
echoes ^A^B. ash claims that these escape sequences elicit undefined
behaviour.

This rule was introduced in the 4.0 branch after 4.0.1, before that
change libjava used to build using ash, proposing this change for the
4.0 branch as well.

Ok to checkin?

	* Makefile.am (Makefile.deps): Don't use non-standardized escape
	sequences in echo command. 
	* Makefile.in: Regenerate.
