Fix and clean code which tests the gcc version
The code which tests whether gcc supports warn_unused_result was wrong. Remove the wrong test from configure and replace it by code using macro QEMU_GNUC_PREREQ in compiler.h. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
