[Qemu-devel] Build failure with make-4.0

[Ken Moffat <zarniwhoop@ntlworld.com>]

Hi,

 I'm working through the packages in Beyond Linux From Scratch in
the expectation that make-4.0 would break something.  Got about
halfway through and started to doubt that.  Then I tried qemu.

 Initially 1.6.0, which failed, so tried 1.6.1 and that fails the
same way.  Found some comments in the June and July archives about
ARFLAGS being empty, and particularly a comment from Peter Maydell
(http://lists.gnu.org/archive/html/qemu-devel/2013-06/msg02952.html)

|However, it's not the cause of the problem:
|
|> ar  libfdt/libfdt.a libfdt/fdt.o libfdt/fdt_ro.o libfdt/fdt_wip.o
|> libfdt/fdt_sw.o libfdt/fdt_rw.o libfdt/fdt_strerror.o
|> ar: two different operation options specified
|
|...which is that the top level makefile is passing ARFLAGS=""
|and so we don't specify any operation to ar at all. For me
|the submake is invoked with ARFLAGS ="rv" (which is Make's
|default for when ARFLAGS wasn't specified).
|
|QEMU's configure and makefile don't fiddle with ARFLAGS at all:
|are you passing some odd values in from your environment?

 So I tried make-3.82 and 1.6.0 built.  Here is the output from
1.6.1 mith "V=1", configured with--prefix=/usr --sysconfdir=/etc
--target-list=x86_64-softmmu (sorry about the reformatting when I
paste) :

 from which I see that ARFLAGS are empty

 and at the place where it fails

 Any suggestions for how to fix this, please ?
