compile C code for iOS armv7+arm64 using clang xcode 9

I'm trying to make one binary for both armv7 and arm64. I am using this command to compile a simple C file:

clang -arch arm64 hello.c -o hello -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk

How can I add armv7 to this command to support old devices like the iPad 4? Knowing that xCode 9 stop supporting armv7 in iOS 11?

As an update to Siguza's answer, the way to get SYSROOT as of Xcode 11 is:

xcrun --sdk iphoneos --show-sdk-path

Just add -arch armv7:

clang -arch armv7 -arch arm64 hello.c -o hello -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk

This will yield a fat binary with both architectures.

Also just a note, you can use xcrun to avoid having to provide the full sys root:

xcrun -sdk iphoneos clang -arch armv7 -arch arm64
