build_sysimg(sysimg_path=default_sysimg_path(), cpu_target="native", userimg_path=nothing; force=false)
Rebuild the system image. Store it in `sysimg_path`, which defaults to a file named `sys.ji`
that sits in the same folder as `libjulia.{so,dylib}`, except on Windows where it defaults
to `JULIA_HOME/../lib/julia/sys.ji`. Use the cpu instruction set given by `cpu_target`.
Valid CPU targets are the same as for the `-C` option to `julia`, or the `-march` option to
`gcc`. Defaults to `native`, which means to use all CPU instructions available on the
current processor. Include the user image file given by `userimg_path`, which should contain
directives such as `using MyPackage` to include that package in the new system image. New
system image will not replace an older image unless `force` is set to true.
