Add new mkspecs device for Raspberry Pi 4 (64-bit)
The existing mkspecs for Raspberry Pi 4 (devices/linux-rasp-pi4-v3d-g++) was intended to compile Qt application for the 32-bit version of Raspberry Pi, thus it used compiler flags that are incompatible when compiling Qt application for the ARM 64-bit architecture. According to ARM compiler documentation, -mfpu flag is rejected by AArch64 state while its alternative, -mcpu, has to be avoided when -march flag is already defined. -mfloat-abi flag is not valid with AArch64 targets.
To support both 64-bit and 32-bit architectures, I proposed to add this new mkspecs.
See:

Pick-to: 6.3 6.4
