deps: fix MacOS and Win build for OpenSSL-1.1.1

Because llvm on MacOS does not support AVX-512, asm files need to be limited to
AVX-2 support even when they are generated on Linux.  fake_gcc.pl returns the
fake llvm banner version for MacOS as if the assembler supports upto AVX-2.

For Windows, makefiles for nmake were updated in OpenSSL-1.1.1 and they are
rewritten into GNU makefile format by hand.
