deps: update asm Makefile for openssl-1.0.2a
This includes following changes,
- Updated asm files for each platforms which are required in
openssl-1.0.2a.
- Some perl files need CC and ASM envs. Added a check if these envs
exist. Followed asm files are to be generated with CC=gcc and
ASM=nasm on Linux. See
`deps/openssl/openssl/crypto/sha/asm/sha512-x86_64.pl`
- Added new 32bit targets/rules with a sse2 flag (OPENSSL_IA32_SSE2)
to generate asm for use SSE2.
- Generating sha512 asm files in x86_64 need output filename which
has 512. Added new rules so as not to use stdout for outputs.
- PERLASM_SCHEME of linux-armv4 is `void` as defined in openssl
Configure. Changed its target/rule and all directories are moved from
arm-elf-gas to arm-void-gas.
