* arm/neon/salsa20-core-internal.asm: Deleted file. This ARM Neon
implementation reportedly gave a speedup of 45% on Cortex A9,
compared to the C implementation, when it was added back in 2013.
That appears to no longer be the case with more recent processors
and compilers. And it's even significantly slower than the C
implementation on some platforms, including the Raspberry Pi 4.
With the introduction of salsa20-2core.asm, performance of this
function is also less important.

conditional as defined(__GLIBC_PREREQ), but move to a nested #if
conditional. Fixes compile error on OpenBSD/powerpc64, reported by
Jasper Lievisse Adriaanse.
