With the below patch I can build either ppc (-m32) or ppc64 (-m64)
versions of Qemu (on a ppc64 host) when passing these compiler flags

You probably meant "without passing"?
Nack. Please don't hardcode -mXX in configure, it's -arch ppc vs.
-arch ppc64 on my host/gcc. What's wrong with passing --extra-cflags?
I posted the following patch today for compiling libcacard with -m32 on
a 64 bit machine.
http://lists.nongnu.org/archive/html/qemu-devel/2011-05/msg02909.html
It adds LDFLAGS. This works fine on x86-64. Then trying this out on
ppc64 with -m32 in extra-cflags I find the following in config-host.mak
[...]
HELPER_CFLAGS=
LDFLAGS=-Wl,--warn-common -g
ARLIBS_BEGIN=
[...]
The -m32 doesn't make it into LDFLAGS. The below patch fixed it for me
following the pattern of x86-64 and i686 a bit further up in the case
statement in configure.
