--- Comment #23 from Alan Modra <amodra at gmail dot com> ---
The segfaults are due to your linker script setting the value of "dot" to near
zero with ". = 0 +  SIZEOF_HEADERS;" then containing a .data output section
with additional contents over the standard .data section.  That extra .data
section then has a vma in the unmapped page at zero (unmapped to catch NULL
pointer dereferences).  Unsurprisingly you get segfaults in the loader.  If the
linker uses your script with -T, which seems to be the intent, the the whole
binary is mapped low.  Segfaults again.

The linker script is plainly and obviously broken.  Newer linkers are simply
doing as asked.  Closing, please don't reopen.
