Comment # 1 on bug 1149995 from Richard Biener

Confirmed.  Also libcaca2 but not others.  The weird thing is that there _is_
debuginfo but only the early part, and no debug info from the ltrans units at
all...

Ah, -g is not taken from the compile-step, so all links not done with explicit
-g end up without debuginfo (I think there's a bug about that).

We used to have code in lto-wrapper recognizing -g0 but that went away with
no longer partially linking the early debug data (but it needed explicit -g0
at link-time).
