| |
When libelf headers and libs are not found and CONFIG_UNWINDER_ORC is selected, there is a make error introduced by commit 3dd40cb320fe ("objtool: Upgrade libelf-devel warning to error for CONFIG_ORC_UNWINDER").
Host headers and libs may be in a non-standard location and the check is performed without host flags. Make sure to use host flags for the check (they will be used later when building objtool anyway).
