JDK-8037953 configure usability: Should provide better details on imported hotspot

[Erik Joelsson]

Hello Dave,

Adding this information certainly makes sense. While probably not a very 
common usecase, it is currently possible to point 
"--with-import-hotspot" to the dist directory of a Hotspot build. The 
problem then is that there will be no java launcher present to query for 
version information. Could you please add a condition on the existance 
of $with_import_hotspot/bin/java before trying to run it? If it's not 
there, the version will simply be unknown.

The patch looks like it's missing indentation. This might be because of 
formatting in JIRA, but in case it's not, please indent the if 
statements properly with 2 spaces.
