Starting with NDK r19 everything you need can be found in the <NDK>/toolchains/llvm/prebuilt/<host> directory.

Stripped down example for arm64-v8a targeting API 28:

export ANDROID_NDK_ROOT=/path/to/android-ndk-r19c
export PATH=$ANDROID_NDK_ROOT/toolchains/llvm/prebuilt/darwin-x86_64/bin:$PATH

SYSROOT=$ANDROID_NDK_ROOT/toolchains/llvm/prebuilt/darwin-x86_64/sysroot
AS=aarch64-linux-android28-clang
CC=aarch64-linux-android28-clang
CXX=aarch64-linux-android28-clang++
ARCH=aarch64
CPU=armv8-a    

./configure \
    --sysroot=$SYSROOT \
    --as=$AS \
    --cc=$CC \
    --cxx=$CXX \
    --target-os=android \
    --arch=$ARCH \
    --cpu=$CPU \
    --enable-cross-compile \
    [ ... other configure options ...]
