[RFA:] sim-config.c: When having a bfd, don't just check bfd_little_endian

[Hans-Peter Nilsson <hans-peter.nilsson@axis.com>]

The testcase for this bug looks like this:
---------------------
# mach: crisv32
# output: 0\n0\n4\n42\n
# sim: --cris-naked --target binary --architecture crisv32 
# ld: --oformat binary

; Check that we can run a naked binary with the same expected
; results as an ELF "executable".

 .include "bare1.ms"
---------------------

That is, we try and run a binary file with a specified
architecture and test output as with the ELF.  Current behaviour
is to emit:

Target (LITTLE_ENDIAN) and specified (BIG_ENDIAN) byte order in conflict
0
0
4
42

which is clearly wrong; BIG_ENDIAN isn't *specified* neither
should it be perceived as such for a binary file.

Ok to commit?

	* sim-config.c (sim_config): Recognize when a bfd has unspecified
	endian information.
