[Buildroot] qtwebkit illegal instruction problem with external toolchain

[Matt Johnson]

Haven't tested webkit, but this is probably the same issue I've been finding
in lots of other packages.  CodeSourcery is a multilib toolchain, and it
picks its library based on the machine architecture flag (-march).  It
assumes armv5te by default, so it is critical when you are targeting one of
the other libraries like armv4t or armv7-a (thumb) to provide -march to the
package.  This is part of the $(TARGET_CFLAGS) variable, but some packages
don't pass it properly.

My git head is ca2b65a6515800991dae49d1815b7bb933f4015c.
Compile qt including webkit with external toolchain (codesourcery default
from selection).

Use simple qt code to test webkit:
int main(int argc, char *argv[])
{
        QApplication a(argc, argv);
        QWebView *view = new QWebView();

 
view->load(QUrl("http://mrdoob.com/projects/chromeexperiments/ball_pool/"));

	view->showFullScreen();
        return a.exec();
}

After app. starting it failed with Illegal instruction (don't check deeply).

Do same with buildroot builded toolchain (default selection just add WCHAR
and C++ support to be able compile QT).
Application work fine without problem.
