It seems I forgot to mention one point in the previous message.

Please, set luajit_ar variable and use it below, not reassign CMAKE_AR.
`include(luajit)` directive does not open a new variables scope, so if
we'll reassign CMAKE_AR here, it may affect static libraries creation
for code outside luajit. We should not change outside build rules in
luajit.cmake.
