Workaround for RSA on AArch64 Big Endian
10646160125 introduced and optimized RSA NEON implementation
for AArch64 architecture, namely Cortex-A72 and Neoverse N1.
This implementation is broken in Big Endian mode, which is not
widely used, therefore not properly verified.
Here we disable this optimized implementation when Big Endian
platform is used.
