There are some files in compiler-rt that use UTF-8 characters in some of the
comments. This causes lint failures with some versions of Python. This patch
just makes the encoding explicit in the call to open.
Python may not be /usr/bin/python on some systems. For example, on
FreeBSD it will be /usr/local/bin/python.
