Comment (by ballapete):

 The prebuilt GO files are:

 {{{
 -rw-r--r--  2 macports  admin   87053 21 Apr  2017 prebuilt/32-bit-big-
 endian-broken/ice-9/eval.go
 -rw-r--r--  2 macports  admin  384293 21 Apr  2017 prebuilt/32-bit-big-
 endian-broken/ice-9/psyntax-pp.go
 }}}

 (notice that they exist in two hard links), my own builds are:

 {{{
 -rw-r--r--  1 macports  admin  104389  3 Sep 02:11 bootstrap/ice-9/eval.go
 -rw-r--r--  1 macports  admin  679597  3 Sep 10:38 bootstrap/ice-9
 /psyntax-pp.go
 }}}

 The `file` commands reveals that they all are of the same kind: `ELF
 32-bit MSB shared object, no machine, version 1 (embedded), not stripped`.
 A closer look onto the hard linked prebuilt files receals:

 {{{
  76892014     88 -rw-r--r--   2 macports admin       87053 Apr 21  2017
 prebuilt/32-bit-big-endian-broken/ice-9/eval.go
  76892024    376 -rw-r--r--   2 macports admin      384293 Apr 21  2017
 prebuilt/32-bit-big-endian-broken/ice-9/psyntax-pp.go
  76892014     88 -rw-r--r--   2 macports admin       87053 Apr 21  2017
 prebuilt/mips-unknown-linux-gnu/ice-9/eval.go
  76892024    376 -rw-r--r--   2 macports admin      384293 Apr 21  2017
 prebuilt/mips-unknown-linux-gnu/ice-9/psyntax-pp.go
 }}}

 Could this be the answer while they are broken? Built on (presumingly 32
 bit) MIPS hardware?
