Lower ARM architecture requirement for CRC32 instructions.

Browse Source 
The changes ensure compatibility with compilers targeting ARMv7.
32-bit processors of architecture 8 and higher, or 64-bit processors running in 32-bit mode can have the CRC32 instructions.
With this change we will query the processor instead of the compiler architecture.
