Ignore __real@ and __TI3? prefixed symbols in ldump
Ignore __real@ and __TI3? prefixed symbols in ldump

The __real@ ones are storage of (shared?) floating-point
constants. The __TI3?  ones are related to throwing exceptions, TI
perhaps means type information. Trying to export them causes
unresolved externals problems, and most likely it would be insane to
export them from a LO DLL anyway. I came across the problem with some
framework DLLs.

Why this issue has popped up now, after the big stlport/boost/etc
change, I have no idea. One would think we have had floating-point
constants all the time in the code, and we throw exceptions all over
the place. Oh well.
