.config file of buildroot 2011.08

When compiling/installing Qt with buildroot, also the qmake.conf is correct.
When buildroot is compiled with the "-O2" flag, the QMAKE_CXXFLAGS of
qmake.conf also includes the "-O2" flag, which causes that all builds (even the
DEBUG ones) are compiled with "-O2", and thus the debugger goes crazy ;)

I would suggest, that when writing the QMAKE_CXXFLAGS (and QMAKE_CFLAGS) to
qmake.conf, we should filter the flags (e.g. -pipe is ok).
