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).
Fixes: 3b27a0c85d70 ("objtool: Detect and warn if libelf is missing and don't
break the build")
