installation of pods fail on Apple M1 chip

[manishprakharan067]

Also I followed this #544
which has same issue
but am not able to figure out where is the part i am missing.

I am getting the following error

`[!] /bin/bash -c

PLATFORM_NAME="${PLATFORM_NAME:-iphoneos}"
CURRENT_ARCH="${CURRENT_ARCH}"

if [ -z "$CURRENT_ARCH" ] || [ "$CURRENT_ARCH" == "undefined_arch" ]; then

Xcode 10 beta sets CURRENT_ARCH to "undefined_arch", this leads to incorrect linker arg.

it's better to rely on platform name as fallback because architecture differs between simulator and device

if [[ "$PLATFORM_NAME" == "simulator" ]]; then
CURRENT_ARCH="x86_64"
else
CURRENT_ARCH="arm64"

fi

export CC="$(xcrun -find -sdk $PLATFORM_NAME cc) -arch $CURRENT_ARCH -isysroot $(xcrun -sdk $PLATFORM_NAME --show-sdk-path)"
export CXX="$CC"

Remove automake symlink if it exists
if [ -h "test-driver" ]; then
rm test-driver
