Maciej W. Rozycki fa3b131151 PR ld/26288: Allow the use of `--just-symbols' with ET_EXEC input 
Fix a regression from commit a87e1817a4 ("Have the linker fail if any
attempt to link in an executable is made.") and do not reject ET_EXEC
input supplied with the `--just-symbols' option.  Such use is legitimate
as the file requested is not actually linked and only the symbols are
extracted. Furthermore it is often the most useful application, as
already observed in our documentation for the option, where it allows
"to refer symbolically to absolute locations of memory defined in other
programs."

Provide a set of tests for the use of ET_EXEC with `--just-symbols'.
These are excluded however for SH/PE targets because they complain if a
section's VMA is 0:

ld: zero vma section reloc detected: `.text' #0 f=32795
ld: zero vma section reloc detected: `.data' #1 f=291

and for x86_64/PE targets because they seem to hardwire the VMA:

 100000000 12000000 01000000 00000000 00000000  ................
