James would be more in tune with what the PS4 linker supports than I am, but in the compiler we don't do arbitrary linker options.  We support specifying libraries (a-la `pragma comment lib`) and dllimport/dllexport names.  The proposed patch could be used for the former but I think not the latter.  It's also not clear whether our mechanism for dllimport/dllexport is optimal, but it keeps us away from all the angst about trying to pervert ELF visibility into supporting it.
