The *.rpo discovery can be many thousands of syscalls too for larger
links and I think -frepo is quite rarely used.
Can't tlink just take into account that sometimes different
symbols mangle the same, and handle those as a group (i.e. if
the linker output requests S::~S(), and *.rpo files contain
several _ZN1SD[0-9]Ev symbols, mark or tweak them all)?
