configure: add gcc version check for ARM Neoverse-N1 platform

Browse Source 
When doing debug build on ARM Neoverse-N1 platform, if gcc version is
lower than 8.4.0, we may met following errors:

/tmp/cc24qua1.s: Assembler messages:
/tmp/cc24qua1.s:53: Error: selected processor does not support `casp x0,x1,x2,x3,[x4]'
/tmp/cc24qua1.s:85: Error: selected processor does not support `caspa x0,x1,x2,x3,[x4]'
/tmp/cc24qua1.s:117: Error: selected processor does not support `caspl x0,x1,x2,x3,[x4]'
/tmp/cc24qua1.s:149: Error: selected processor does not support `caspal x0,x1,x2,x3,[x4]'

The change also fix the problem by pass armv8.2-a+crypto as target architecture.
