curl-compilers.m4: fix unknown-warning-option on Apple clang
Since 5598b0bd63f690c151074494ce47ef872f004ab4, clang -v is used to detect the clang version. The version number was expected to come after the word "version". For Apple clang, this doesn't work as it has its own versioning scheme. The version number is now first searched after the string "based on LLVM". This works for Apple clang before version 7, and also for e.g. Ubuntu's clang up to version 3.7. If it's not found and the version string contains "Apple LLVM version", clang version 3.7 is assumed, which is the version that comes with Xcode 7. Otherwise, the version number is still expected after the word "version", which works for very old Apple clang versions.
