XCode 8.0 breaks builds

[asfimport]

Exactly the same as ARROW-93. The fix is the same as well. I can submit a patch if desired.

Environment: Mac OS X, XCode 8.0, Apple LLVM version 8.0.0 (clang-800.0.38)
Reporter: Christopher Aycock / @chrisaycock
Assignee: Christopher Aycock / @chrisaycock

_{Note: This issue was originally created as ARROW-313. Please see the migration documentation for further details.}

Dan Robinson / @danrobinson:
Probably worth just matching on "clang-**" this time, so we don't have to do this again when XCode 9 comes out. I think it's a safe enough assumption that "clang-**" will always mean clang is the compiler family.

Julien Le Dem / @julienledem:
I just ran into the same issue.
Do we want to generalize the string a bit? (so that works with 9.0.0 as well?)
Patch welcome @chrisaycock.

(Escaped asterisk to get JIRA formatting to work; the pattern shouldn't actually include a backslash)

Christopher Aycock / @chrisaycock:
Does everyone agree with just searching for "clang-\*"? You can assign the issue to me and I'll submit a patch.

Julien Le Dem / @julienledem:
I agree.
@wesm, @xhochy: thoughts?
