5fd6637b4d * Decide whether to use BeOS style symbol resolution at run time
depending on the gcc version of the executable.
* Adjusted non-BeOS-style symbol resolution so that add-ons and
  dynamically loaded libraries find symbols in the executable.

This change re-enables support for undefined symbols.

3498280968 The runtime loader now reads a part of the .comment section of each
shared object to find out the GCC version it has been compiled with.
This is not an exact science, since we've got the version string for
every single object file that has been linked in, but my heuristic seems
to be good enough.

Having the gcc version at hand will allow for two features: Enabling
work-arounds for old executables (like the type info problem in BeOS
apps), and automatically selecting the right set of libraries in a mixed
gcc 2/gcc 4 environment.

fe7f3a2f1d Now supports symbolic links correctly, and no longer loads the same shared
library twice.

28e0d4cd19 The runtime loader now creates a debug area through which other teams can
access a team's internal loader data.
