bash configure fails on missing javah

Note the corollary is that this impacts when javac can use recent 
language features.  i.e. in order to build the "interim javac", the  
javac source code must be compatible with the "boot JDK". There's 
nothing inherently new in that, but the new release schedule is 
definitely going to have an impact here.
