[kaffe] Compilation failed for NetBSD1.6

Hi,

Latest snap failed on ia32/nb1.6 while configure.

According to the log,
>Information: Using pure Java math library
>checking which extensions to include... 
>checking if malloc debugging is wanted... no
>checking for kaffe... no
>checking for java... no
>configure: error: no acceptable Java virtual machine found in $PATH

Yes, I don't install 'java' on this machine, and the check result is
correct :-)

And according to 'configure', this checking is required because I don't
specify '--disable-gjdoc', but until recently gjdoc was generated by
the newly built (if successful) java and javac, rather than relying on
existing java. Of course I understand the workaround for this is to
specify '--disable-gjdoc' while configure, but hope to have smarter
solution.
