Only partially.  Typical linker output on a current GNU/Linux system
includes a PT_GNU_STACK and a PT_GNU_EH_FRAME segment.  There is no way
to describe those segments in the current linker script language.  As
far as I can see, any attempt to add them with the current semantics
would amount to saying "created magically," and as such would add
little.  Similarly, although the PT_GNU_RELRO segment is partially
represented in the current linker script language via
DATA_SEGMENT_RELRO_END, little tricks like putting the first few
.got.plt entries into the relro segment can not be represented in the
current linker script language.
