## Test that non-alloc section .foo can be assigned to a segment. Check that
## the values of the offset and file size of this segment's PHDR are correct.
##
## This functionality allows non-alloc metadata, which is not required at
## run-time, to be added to a custom segment in a file. This metadata may be
## read/edited by tools/loader using the values of the offset and file size from
## the custom segment's PHDR. This is particularly important if section headers
## have been stripped.
