luajit @ 2.0.5 : Does not compile on Catalina with Xcode 11.1, CFLAG patch and link below

[justinGilmer (Justin Gilmer)]

I was trying to install Neovim @ 0.3.8 , which requires luajit. However, when attempting to build luajit @ 2.0.5, the error listed below occurs.

I found this apple developer thread which was discussing some compiler issues with Xcode 11.1 and that adding the CFLAG -fno-stack-check or changing the deployment target to 10.14 would provide a workaround. I chose the former, which is included below in my attached patch file. I was then able to successfully install luajit and Neovim.
