bug#26966: [PATCH 15/22] gnu: icedtea-7: Use icedtea-6 for bootstrapping.

[Ricardo Wurmus <rekado@elephly.net>]

* gnu/packages/java.scm (icedtea-7)[source]: Remove Makefile.in patch to link
with GCJ libs.
[arguments]: Remove (ice-9 rdelim) module; adjust configure flags; do not add
GCJ headers to CPATH in build phase "set-additional-paths".
[native-inputs]: Remove gcj, add icedtea-6.
(icedtea-8)[native-inputs]: Delete "icedtea" from the inherited inputs, not
"gcj".
