compiler-rt: Drop a workaround to build for aarch64

This workaround seems to no longer be needed for clang6.0 onwards
as a bonus, the regressions for compiling for other arches is also gone
since we drop this patch.

Fixes issue #57
Fixes issue #52

Use internal assembler

This fixes the issue reported here

-Subject: [PATCH 5/5] Pass -march=armv8.1-a instead of -mcrc
-
-When we pass -mcrc it does not cause driver to
-pass right options to assembler, especially when
-using GNU assembler, is used this causes assembler
-failures to recognise crc instructions since the
-default -march option passed it armv8-a
-
-/tmp/scudo_crc32-9e9612.s:14: Error: selected processor does not support `crc32cx w0,w0,x1'
-
-Adding -march=armv8.1-a forces the driver to pass
--march=armv8.1-a to assembler as well, which fixes
-this issue
