Defconfig to reproduce the problem

Current Buildroot master (fd08153b9d677) fails building with a minimalistic ARM
Cortex-A8 config with Sourcery CodeBench ARM 2010.09 and just Qt enabled.

This is the make output:

And here's the offending code around line 223:

template <typename T>
Q_INLINE_TEMPLATE bool QBasicAtomicPointer<T>::testAndSetRelaxed(T
*expectedValue, T *newValue)
{
    register T *result;
    asm volatile("0:\n"
                 "ldrex %[result], [%[_q_value]]\n"
                 "eors %[result], %[result], %[expectedValue]\n"
                 "itt eq\n"
                 "strexeq %[result], %[newValue], [%[_q_value]]\n"
                 "teqeq %[result], #1\n"
                 "beq 0b\n"
                 : [result] "=&r" (result),
                   "+m" (_q_value)
                 : [expectedValue] "r" (expectedValue),
                   [newValue] "r" (newValue),
                   [_q_value] "r" (&_q_value)
                 : "cc");   // <--- line 223
    return result == 0;
}

Other errors raise from similar pieces of code.
