[binutils-gdb] BFD_INIT_MAGIC


*** TEST RESULTS FOR COMMIT bf2dd8d7cf4114b8a60dbb83b340f76b9b2474d1 ***

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.
