3539--enable-host-shared typically slows the rest of the compiler down by
3540a few %, so you must explicitly enable it.
3541
3542If you want to build both the jit and the regular compiler, it is often
3543best to do this via two separate configure/builds, in separate
3544directories, to avoid imposing the performance cost of
3545--enable-host-shared on the regular compiler.])
