Xcode 9 and 10 need some stubs

[woachk]

This prevents running Xcode 9 CLI tools or any other recent Swift version.

XCode comes with a version of make, so I just replaced the "system" one with that.

[PhilipDeegan]

There's more

NSAffectedObjectsErrorKey
NSPersistentStoreSaveConflictsErrorKey
NSValidationKeyErrorKey
NSValidationObjectErrorKey
NSValidationPredicateErrorKey
NSValidationValueErrorKey

and now also

dyld: Symbol not found: _OBJC_CLASS_$_NSMergeConflict```

Next ones needed:

I'm quite ignorant to the internals of all this, but I recall using the same version of XCode previously and not having such problems - maybe I'm mistaken/confused

thanks for your time @ahyattdev

Hi Dekken,

I am going off of all the symbols that the main 'Xcode' application executable relies on here. I'm not sure exactly which program is being run that creates this issue but hopefully this also fixes that.

[ahyattdev]

Next is _kSecAttrAccess.

[ahyattdev]

Next is _NSAccessibilityActivationPointAttribute, in AppKit.

[ahyattdev]

Next is _NSAccessibilitySupportsMainThreadIdleNotificationAttribute, in AppKit

[ahyattdev]

Next is _kCGWindowAlpha, in CoreGraphics. I will be away for a few days, will pick up later.

[ahyattdev]

Next is _OBJC_CLASS_$_NSScriptCommand in Foundation.

[ahyattdev]

Next is _OBJC_CLASS_$_CAReplicatorLayer in QuartzCore.

[ahyattdev]

Next is _NSAnimateBinding in AppKit.

Xcode 10 finally has all the symbols it wants before it starts executing any code. It of course does not work yet, but that is outside of the scope of this issue.

For those who are curious, this is what happens when it is run:

objc[23]: Class CIAffineTransform is implemented in both /System/Library/Frameworks/CoreImage.framework/Versions/A/CoreImage (0x7ffff01a3b20) and /System/Library/Frameworks/QuartzCore.framework/Versions/A/QuartzCore (0x7ffff36e4860). One of the two will be used. Which one is undefined.
Assertion failed: (isRealized()), function isMetaClass, file /home/andrewhyatt/darling/src/external/objc4/runtime/objc-runtime-new.h, line 1221.
Abort trap: 6 (core dumped)
