bfd: patch for missing strtoull

[Aldy Hernandez <aldyh at redhat dot com>]

hi guys!

MacOS X does not have strtoull so bfd doesn't build.  *sigh*  

here is a patch to add configury magic to check for strtoull, and if not
available, use our own version of strtoull (stolen from newlib).

is this the right approach?

ok to install?

Cheers.
