qemu: fix failure to find zlib header files during configure

Corrects problems during configure of qemu-native due to the BUILD_CFLAGS
not being included when attempting to compile the test program for zlib
within the configure script.

+In native builds, qemu can fail to find zlib development files in the native 
+sysroot and the build machine might not have zlib-dev packages installed.
+
+Add CFLAGS to qemu's CFLAGS which in the native case means BUILD_CFLAGS are
+added and files in the sysroot can be found.
