This patch will obviously do bad things when reading the symbols of a
shared library that exports versioned symbols. It'll record the same
symbol name with different addresses... silly me.
At the very least it should be limited to the main executable (where we
can't have multiple versions of the same symbol defined).
Should I post an updated patch, or does anyone think this simple
special-casing approach is a no-go?
