Link with -lm for log()
Without this change, I’m getting the following error:
cc blocksplitter.c cache.c deflate.c gzip_container.c hash.c katajainen.c lz77.c squeeze.c tree.c util.c zlib_container.c zopfli_lib.c woff.c sfnt2woff.c -o sfnt2woff-zopfli -lz

The manpage log(3) mentions “Link with -lm.”, which this change does.
