init: lto: fix PREL32 relocations
With LTO, the compiler can rename static functions to avoid global naming collisions. As initcall functions are typically static, renaming can break references to them in inline assembly. This change adds a global stub with a stable name for each initcall to fix the issue when PREL32 relocations are used. Signed-off-by:Sami Tolvanen <samitolvanen@google.com> Reviewed-by:
