lib: luajit: only require a C compiler

[ThomasDevoogdt]

Upstream: zhaozg/luajit-cmake#17

@cosmo0920 Can you also check this one, and add the milestone tag?

luajit-cmake's upstream is here: https://github.com/zhaozg/luajit-cmake
But this repo does not seem actively to accept external contributors' PRs.
Is this adding milestone tag good way to us, @edsiper ?

@edsiper @cosmo0920 Upstream has merged this commit, so I think it can be merged here.

I'm going to process other commits for cross compiling of ARM64 on x86_64 platform. So, we should hold on this patch for now.

Hi, can you also consider #9600 if you're busy with fixing cross compiling issues?

I use approved status to mark this PR is valid but we need to merge the bundled libraries should be merged into upstream at first and we'll merge the changes with upstream syncs.
