The motivation for this fork was to compile BWA on arm as well as intel architecture.
## Changes
The changes here are copied from the pull request on the main BWA repository: lh3#344
We use the header file sse2neon.h
(https://raw.githubusercontent.com/DLTcollab/sse2neon/7393a4a114d6611055e87c4bb5ceee8426893973/sse2neon.h)
and edit ksw.c to use that header file if USE_ARM is set.
Then edit the Makefile to detect if the architecture is arm or not,
and set USE_ARM if it is.
