[PATCH] Obvious fix of -feliminate-dwarf2-dups

[Zdenek Dvorak]

Hello,

the size of die is computed incorrectly if there are references to
other CU's; I am commiting the attached patch as obvious.

Changelog:
        * dwarf2out.c (size_of_die): Compute size of external reference
        to die correctly.
