[Buildroot] [PATCH] package/libbsd: further reduce the set of supported archs

[Yann E. MORIN]

From: "Yann E. MORIN" <yann.morin.1998@free.fr>

Support for a,out on ARM will be dropped in Linux 3.11 (and is already
missing in the -rc).

m68k is marked BROKEN in Buildroot, so it is never ever tested.

The x86 familly is the only one left with support for a.out, now.

Hmm...  It looks like support for a.out may be removed using
-D__NO_A_OUT_SUPPORT. Although, a.out.h is always included, even with
this flag.

We may patch the code instead of disable architectures?

(In add, we may bump to 0.6.0)

You may also update comment.

See the discussion with Thomas, starting with my analysis here:
    http://lists.busybox.net/pipermail/buildroot/2013-August/076659.html
and with Thomas' answer here:
    http://lists.busybox.net/pipermail/buildroot/2013-August/076661.html

Yes, maybe.
