Patch from: https://github.com/bpftrace/bpftrace/pull/3648
From 986acde60552af60c0a28aac234c38a7542d2f69 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix ODR violation warning when compiling with LTO
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
yy_scan_string is declared to return void* due to a lack of a proper
type definition of struct yy_buffer_state, which is only available in
lex.yy.cc. Provide a struct forward declaration so that a proper
return type can be used. This fixes the LTO complaint.
