[BUG] gcc: require neon on arch without neon

[BUG] gcc: require neon on arch without neon

[Yi Qingliang]

when compiling qtbase in meta-qt5, it says:
| ../../include/QtCore/../../../git/src/corelib/global/qendian.h:143:36:
fatal error: You must enable NEON instructions (e.g.
-mfloat-abi=softfp -mfpu=neon) to use these intrinsics.
|      return __builtin_bswap16(source);
|                                     ^
