Provide an alias to _obstack_free
GDB 7.11 does not build if compiled against uclibc-ng (1.0.12 was used, but the problematic code exists in 1.0.13 as well). The reason is that GDB release includes its own obstack implementation, but elides the code if <gnu-versions.h> declares a compatible obstack implementation in libc. uclibc-ng does claim compatible obstack interface (GDB expects version 2, but accepts version 1 if sizeof(int) == sizeof(size_t)), however, uclibc-ng does not provide the _obstack_free symbol that is a part of the interface (glibc does provide this symbol). This later causes a link failure. The attached patch makes uclibc-ng enables an alias _obstack_free -> obstack_free. Signed-off-by: Alexey Neyman <stilor@att.net>
