Comment:
I implemented a support for ELF weak symbols on Linux. The implementation
follows hgolden's design above, except that it doesn't support undefined
weak symbols. The change is implemented in 3 patches: the first one
simplifies the code, the second one implements the support, and the third
one adds a special symbol !__dso_handle. This is not directly related to
weak symbols, but is required to load C++ object files.
