RFR(S): 8145560: AIX: change '8036003: Add --with-debug-symbols' broke AIX build

[Volker Simonis]

Hi,

could somebody please review and sponsor (regeneration of
'generated-configure.sh' is required) the following small change:

http://cr.openjdk.java.net/~simonis/webrevs/2015/8145560/
https://bugs.openjdk.java.net/browse/JDK-8145560

Change 8036003 introduced the the '--with-native-debug-symbols'
configure option the default of which is set to 'zipped'.

On AIX we can not generated external debug info and hence we also can
not zip it. Currently the build breaks because of the missing
dependencies from .diz to .debuginfo files.

The fix is simple - make 'internal' the default value for the
'--with-native-debug-symbols' configure option on AIX.

Thank you and best regards,
Volker
