Delete _bdf_ecoff_archive_p

[Alan Modra <amodra at bigpond dot net dot au>]

This patch removes _bdf_ecoff_archive_p, which is virtually a copy of
bfd_generic_archive_p.  The differences are that the generic function
has a bug fix and allows b.out archives, and the ecoff version calls
its slurp_armap and slurp_extended_name_table directly rather than
via BFD_SEND.  ie. the only practical difference is allowing b.out
archives.  I don't think that warrants a separate function.

	* ecoff.c (_bfd_ecoff_archive_p): Delete.
	* libecoff.h (_bfd_ecoff_archive_p): Delete.
	* coff-alpha.c (ecoffalpha_little_vec): Use bfd_generic_archive_p.
	* coff-mips.c (ecoff_little_vec, ecoff_big_vec): Likewise.
	(ecoff_biglittle_vec): Likewise.
