[rfc] Program to check bfd_format vector

Hi Andrew,

when: Any time the binutils testsuite is run.

      (If this test ever fails then the BFD API is broken and we cannot 
expect other binutils tests to necessarily work correctly).

Where: In the binutils testsuite:  binutils/testsuite/binutils-all.

Cheers
