As Zack said, it's needed to support -frepo.

Mind you, -frepo support does not require the fork/exec code in
collect2.  In fact, it would be possible to use some judicious #ifdefs
to remove the fork/exec code from collect2 for almost all
targets--specifically all targets which do not have use_collect2=yes
in config.gcc.  I think the only interesting targets which have
use_collect2=yes, and therefore do require the fork/exec code, are
HP/UX, AIX, and OpenBSD.
