libc/misc/gnu/obprintf.c: implement obstack_printf and obstack_vprintf
This adds a straight forward implementation for obstack_printf and obstack_vprintf on uClibc's already existing obstack_grow and vasprintf. It does not attempt to port over glibc's implementation in terms of _IO_* structs and functions. Signed-off-by: Anthony G. Basile <blueness@gentoo.org> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
