BFD_INIT_MAGIC
This patch performs a run-time test that a shared libbfd.so has been compiled with the same size bfd_vma as that of apps using the library. On a 32-bit host it is easily possible to have one libbfd.so compiled to support 64-bit targets (or configured with --enable-64-bit-bfd) while another only supports 32-bit targets. The two libraries will have differently sized bfd_vma types, and if the wrong one is loaded all sorts of weird behaviour might be seen. bfd/ PR 23534 * init.c (BFD_INIT_MAGIC): Define.
