Ewww!

Sorry to rain on your parade, but are you sure this (and with the fix for
the nested expansion, it becomes even more ugly) is compatible with the
"spec files must be legible" packaging guideline?

That is a valid point. I don't know what is better,
Well, a Shell Function would be more readable, for example. It would
accept normal arguments to fill in variables -- instead of global RPM
macros, which are substituted in the entire spec file.
Uhm, how can one this be done? Shell variables are substituted after macro expansion, so i.e.

function do_build {
arch=$1
qt_version=$2
%{mingw${arch}_qmake_${qt_version}}
}

would hardly work? Or are you suggesting passing the entire macros as arguments? I.e.

function do_build {
qmake=$1
make=$2
${qmake} <args>
${make} %{?_smp_mflags}}
[...]
do_build "%{mingw32_qmake_qt4}" "%{mingw32_make}"
