3573--enable-host-shared typically slows the rest of the compiler down by
3574a few %, so you must explicitly enable it.
3575
3576If you want to build both the jit and the regular compiler, it is often
3577best to do this via two separate configure/builds, in separate
3578directories, to avoid imposing the performance cost of
3579--enable-host-shared on the regular compiler.])
