Workaround lldb issue with main module base address

Browse Source 
On FreeBSD lldb sometimes reloads the the main module's (executable's)
symbols at the wrong address.  Work around this for now by explicitly
reloading at base_address=0 when it happens.

A proper fix is needed but early testers have reported this issue so
this workaround should allow them to make further progress.
