Kernel provides virtual DSO for stack unwinding/exception handlind info for signal usage case. Stack unwinding routines use 'dl_iterate_phdr' function for additional DWARF info gathering from DSOs. Patch enables virtual DSO enumeration via dl_iterate_phdr function. Signed-off-by: Sergey Melnikov <sergey.melnikov@intel.com> Change-Id: Ic2882b28f40b456a088bc1e63c50cbfda7e4a102
