build fail when __LP64__ is not defined

[welbonwang]

LP64 is not defined default when build for armv7. line 89 causes a error. It might be #ifdef __LP64__ instead of #if __LP64__

I am not able to reproduce this problem. Can you provide more details, such as: how exactly are you building? What is the exact compiler error output you are seeing?

[welbonwang]

reproduce command as following:

clang -D__KERNEL_ARM_ARCH__=7 -arch armv7 -isysroot /Applications/Xcode10.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk -Wall -Wundef -Werror -c -o fishhook.o fishhook.c

and errors

fishhook.c:89:5: error: '__LP64__' is not defined, evaluates to 0 [-Werror,-Wundef]
#if __LP64__
    ^

I use Xcode 10.0.1
