Comment (by ballapete):

 The same on `PPC Leopard, Mac OS X 10.5.8`:

 `-E cmake_link_script` seems to be some option and argument for CMake, and
 `build/CMakeFiles/openblas_shared.dir/link.txt` contains what `port` has
 logged. The `.rsp files` are:

 {{{
 -rw-r--r-- 1 macports admin       6 19. Aug 12:39 linkLibs.rsp
 -rw-r--r-- 1 macports admin  130982 19. Aug 12:40 objects1.rsp
 -rw-r--r-- 1 macports admin  130935 19. Aug 12:40 objects2.rsp
 -rw-r--r-- 1 macports admin  130975 19. Aug 12:40 objects3.rsp
 -rw-r--r-- 1 macports admin   38352 19. Aug 12:40 objects4.rsp
 }}}

 `@CMakeFiles/openblas_shared.dir/linkLibs.rsp` only contains:

 {{{
  -lm
 }}}

 The other four `.rsp files` are all one very long line… (∑ ≈ 560 K
 characters)
