>Description:
	1. make depend  at  src/gnu/lib/bfd  generates this warning:

% make depend
 (...snip)
/usr/src/gnu/lib/bfd/../../dist/bfd/elf32-m68k.c:1823: elf32-target.h: No such file or directory

	2. make -j 4  (cross compilation on 4CPU machine) at
	   src/gnu/lib/bfd fails with an error like the following,
	   even though you have run  make depend  beforehand.

% make -j 4
--- elf32-m68k.so ---
--- archive.o ---
--- archive.so ---
--- archures.o ---

/usr/src/gnu/lib/bfd/../../dist/bfd/elf32-m68k.c:1823: elf32-target.h: No such file or directory
*** Error code 1
1 error

	3. libbfd.c  is unexpectedly archived in the  libbfd.a .

% make -j 1
 (...snip)
building standard bfd library
/usr/src/gnu/lib/bfd/../../dist/bfd/libbfd.c: not object file or archive

>How-To-Repeat:
	See above.

>Fix:
	Apply this patch to src/gnu/lib/bfd .

	1. Add elf{32,64}-target.h to the SRCS macro.

	2. This problem is due to the missing of dependency of *.so.
	   The fix of 1. also fixes 2. with make depend,
	   but the following patch to Makefile (2nd hunk) allows make
	   without make depend, which may be convenient.

	3. An undocumented :-) special target  .INVISIBLE
	   seems usable to solve this.
	   But, I'm not sure this is a correct solution....
