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