unsupported option in 47/mkspecs/linux-g++-maemo/qmake.conf

(I was not sure whom to assign, please help in routing this item to correct team, thanks.)

Commit 69d9e773 adds '-Wno-psabi' option to compiler flags. To my understanding this feature is only supported from GCC 4.4 onwards.

This becomes an issue when doing the default scratchbox installation for Maemo5 (e.g. following guides in
http://wiki.maemo.org/Documentation/Maemo5_Final_Installation ), as the default toolchain seems to set sbox-arm-none-linux-gnueabi-gcc (GCC) 4.2.1.

The observable end result is that configure for Qt fails at Xlib configure test, at closer look yielding a 'cc1plus: error: unrecognized command line option "-Wno-psabi"'
