[Message part 1 (text/plain, inline)]
This patch fixes an interesting bug in default_target_compile: if the options set dest= prior to specifying a language, the language defaults are loaded incorrectly. Specifically, for each board_info value, the *existence* of that value is tested for the board specified using dest=, but the actual value is
read from the information for the current target. Since the current target is the default destination, the only reason to specify the dest= option is to override the current target, so this must be wrong and this patch fixes the bug.

Subject: [PATCH 8/9] Fix misuse of "target_info" in default_target_compile
*ChangeLog entry:
* lib/target.exp (default_target_compile): Use the "board_info"
procedure correctly when loading language defaults, instead of
checking for each option under the $dest board, but reading the
value using "target_info", which uses the current target instead
of the target specified using the "dest=" option.
