2013-06-14libc/misc/gnu/obprintf.c: implement obstack_printf and obstack_vprintfAnthony G. Basile
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.
