Hi,
How do I prevent rpmbuild from attempting to strip a particular binary? The
problem is that the binary was cross-compiled and is not of the same
architecture as the normal Fedora binutils. Thus the strip program used (from
the wrong binutils) appears to corrupt the binary.

You probably need to disable debuginfo packages if that is the case.
You might also want to redefine %{__strip} to the appropriate
cross-strip utility, or /bin/true. Something like:
%define debug_package %{nil}
%define __strip /bin/true

%define __strip /bin/true
As well as this you may also need to stop prelink from breaking the
cross-compiled binaries. This can be particularly insidious because
the binary will work after installation right up til the next
overnight prelink run.
Here's how to stop prelink:
%install
...
mkdir -p $RPM_BUILD_ROOT/etc/prelink.conf.d
echo '-b /usr/bin/name' > $RPM_BUILD_ROOT/etc/prelink.conf.d/%{name}.conf

rpmbuild uses eu-strip, not strip. Therefore elfutils, not binutils.
See: /usr/lib/rpm/find-debuginfo.sh
That's if debuginfo packages are enabled. If they aren't it uses
plain strip afaik.

/usr/lib/rpm/redhat/macros
%{!?__debug_package:\
/usr/lib/rpm/redhat/brp-strip %{__strip} \
/usr/lib/rpm/brp-strip:
STRIP=${1:-strip}
/usr/lib/rpm/macros:
%__strip /usr/bin/strip
I see, that is a bug.

Ah, so I can make a shell script to apply the appropriate strip binary...

File it for elfutils, please.
You may also re-test it with trunk:
git://git.fedorahosted.org/git/elfutils.git

That's the same version as I'm using from F-16. I rebuilt it, but it makes no
difference.

Like so:
%define __ar_no_strip $RPM_BUILD_DIR/%{srcdir}/ar-no-strip
cat >%{__ar_no_strip} <<EOF
#!/bin/bash
f=\$2
if [ \${f##*/} = libgcc.a -o \${f##*/} = libgcov.a ]
then
:
else
%{__strip} \$*
fi
EOF
chmod +x %{__ar_no_strip}
%undefine __strip
%define __strip %{__ar-no-strip}
Interestingly, it only seems to be used for static libraries.
