Hi,

Darwin's static linker expects, by default, that all linkage will
be satisfied (even for weak items).  This allows the two-level
namespace to work even for weak cases.

However, there's an option to make it behave in a similar manner
to ELF.  This is needed for the pure-virtual1.C testcase to pass
on Darwin.

tested on x86_64-darwin and linux,
pushed to master
thanks
Iain
