[fpc-pascal] fpc-pascal] Static linking against the indigo cheminformatics package under Linux x64 complains undefined reference to __dso_handle when Free Pascal is used

[Xichen Li]

Dear Joans,

After some digging, it seems that Free Pascal cannot link to C++ object file 
directly, which means Free Pascal cannot link to C++ static libraries 
directly. Runtime Error 216 errorrs.

This feature is on Free Pascal road map.

You also have to link against libc. gcc does that by default, but FPC does 
not.
