Bug 1168

After fixing a do_unpack issue (see first patch in contrib branch qt4-nativesdk-fix1) I have found that qt4-tools-nativesdk fails at compile with the following error:

-------- snip --------


I found the same error message in two separate bug reports:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=623281
http://bugreports.qt.nokia.com/browse/QTBUG-17962

I'm not sure that the first is relevant given that the configure log is reporting:
-------- snip --------
Determining system architecture... (Linux:2.6.35.13-92.fc14.x86_64:x86_64)
    64-bit AMD 80x86 (x86_64)
    'arm' is supported
    'x86_64' is supported
System architecture: 'arm'
Host architecture: 'x86_64'
-------- snip --------

So there is apparently no issue with an unsupported architecture. The second bug report has an attached patch but seems to have been rejected for procedural reasons so the correctness of the patch is unclear.
