There are cases where stub library processing can trigger new exports
which might require them to be included at LTO time.
Specifically `processStubLibraries` marks symbols as `forceExports`
which even effect the LTO process.
And since the LTO process can generate new undefined symbols
(specifically libcall function) we need to also process the stub
libraries after LTO.
