Fix compilation of the BFD sub-directory with a gcc v8 compiler by adding extra casts.

GCC v8 issues warnings about mis-matching casts of function pointers.
A previous patch tried to fix this problem by adding new dummy functions
which accepted a variable number of arguments.  But this introduces serious
problems when compiled with other versions of gcc, (notably gcc 4.4).  This
patch reverts that previous solution and instead adds extra casts (to
function types without a parameter list).

	warnings instead.
