[PATCH] oleaut32: ERR on 32bit typelibs on 64bit

[Marcus Meissner]

Triggered by the Novell Groupwise installer currently,
from the ISBE64W.exe Installshield Helper program.

The typelib is contained directly in ISBE64W.exe itself :/

Basically if we encounter this case the program will crash
anyway (but with random backtrace), so output an ERR().

Ciao, Marucs
