Switch libcompiler_rt-extras to LateStaticLibs.

Bug: http://b/28149048
Test: Rebuild world (and check on new clang dependencies).

The latest clang inserts even more dependencies for
libcompiler_rt-extras (in the form of __unorddf2/__unordtf2), so we need
to ensure that it gets linked after libm.a for binaries that statically
pull it in.
