[uclibc-ng-devel] [PATCH 1/2] Advertise obstack only when chosen

This is similar to this patch for GNU glob: ff6ce3999db93a52d1cd22510f8508b660ddf54e. The problem is that libiberty/obstack.c file checks for _GNU_OBSTACK_INTERFACE_VERSION == _OBSTACK_INTERFACE_VERSION and elides libiberty obstack implementation if there is already a compatible implementation in libc. Therefore define should be set only when obstack is actually selected, otherwise it is not possible to build binutils and gdb with uClibc.
