[Qt-interest] [PATCH 1/2] configure: handle shell vars in QMAKE_CXX

[Grant Likely]

The configure script fails if the QMAKE_CXX setting uses an
environmental variable.  For example, $(CROSS_COMPILE) is often used
to set the gcc prefix.  This patch adds a sed command to convert qmake
$() expressions to ${} and passes the result through 'eval' so that the
shell expands it correctly.

This patch makes me feel a bit dirty since it is only a bandaid over the
real problem. The real solution involves implementing full qmake
configuration parsing in shell script, which is not something I'm keen
to take on.
