gdb.base/pending.exp failures

[Daniel Jacobowitz]

Just a note of probable-cause: Jeff, on which platforms did you test
this testcase?  I bet it wasn't i386-linux.

This function is in a shared library that hasn't been loaded yet. 
However, on i386-linux (and many other platforms), the call will go
through a PLT entry, and the entry in the application's symbol table
will appear as an SHN_UNDEF symbol with a non-zero address pointing at
the PLT entry.  GDB will re-resolve the breakpoint after shared
libraries have been loaded.  This is already-existing functionality.

If you don't want to use dlopen in the test, try setting breakpoints on
a function not called directly from the executable (i.e. called from
within the library).
