## This test verifies that loading an ELF file that has no section headers can
## find the contents on the .dynamic section and the strings associated with
## the .dynamic seciton.
## - Loading the .dynamic section from the PT_DYNAMIC
## This test will make a simple executable that links against libc.so and we
## verify that we can find the DT_NEEDED entry with the shared library found
## in the .dynamic dump from "image dump objfile"
