Changelog:
Removed ARM assembly implementation (ARM will use pure Go implementation now) because it had a bug #15.
While there was no changes regarding compiler versions, it doesn't make sense to support Go 1.1.
The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.
There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.
