Only build bootstrap classes with source/target 1.6 if the VM doesn't support 1.7 bytecode.
2011-09-30 Andrew John Hughes <ahughes@redhat.com>
* Makefile.am:
(ICEDTEA_BOOT_PATCHES): Only apply
use_target_6_for_bootstrap_classes if 1.7
bytecode is not supported by the VM. Fixes
bootstrap with IcedTea7.
* acinclude.m4:
(IT_BYTECODE7_CHECK): Check if the VM supports
1.7 bytecode.
* configure.ac: Call IT_BYTECODE7_CHECK.
