Remove clang assembler .arch workaround.

This makes it difficult to build against the NDK's toolchain file. The
problem is __clang__ just means Clang is the frontend and implies
nothing about which assembler. When using as, it is fine. When using
clang-as on Linux, one needs a clang-as from this year.

The only places where we case about clang's integrated assembler are iOS
(where perlasm strips out .arch anyway) and build environments like
Chromium which have a regularly-updated clang. Thus we can remove this
now.

Bug: 39
Update-Note: Holler if this breaks the build. If it doesn't break the
   build, you can probably remove any BORINGSSL_CLANG_SUPPORTS_DOT_ARCH
   or explicit -march armv8-a+crypto lines in your BoringSSL build.
