  [AIX][ifunc] fix error message creation logic (misbehaves in production builds) (#188060)

I don't know why the old code was causing the function name to come out
empty in the message, in certain builds of llvm.
It's either a misuse[1] of the Twine class, or a bug somewhere else.
So this PR rewrites the logic by building the message into a
SmallString<128>. This logic is part of error handling, so optimizing it
is not important.

[1] I checked the usage and couldn't find anything suspicious
