Set the flag word in the BFD @var{abfd} to the value @var{flags}.
Possible errors are:
o wrong_format - The target bfd was not of object format.
o invalid_operation - The target bfd was open for reading.

o <<wrong_format>> - The target bfd was not of object format.

The flag word contained a bit which was not applicable to the
