3571--enable-host-shared typically slows the rest of the compiler down by
3572a few %, so you must explicitly enable it.
3573
3574If you want to build both the jit and the regular compiler, it is often
3575best to do this via two separate configure/builds, in separate
3576directories, to avoid imposing the performance cost of
3577--enable-host-shared on the regular compiler.])
