V3 [PATCH] elf: Allow mixed ordered/unordered inputs for non-relocatable link

Hi H.J.

The patch looks good to me, but the new tests do cause problems for
a variety of targets.  For example:

  fido-elf ...         LD REGRESSION: ld-elf/pr26256-3a  ld-elf/pr26256-3b
  fr30-elf ...         LD REGRESSION: ld-elf/pr26256-2b
  mipsel-linux-gnu ... LD REGRESSION: ld-elf/pr26256-3a  ld-elf/pr26256-3b
  riscv32-elf ...      LD REGRESSION: ld-elf/pr26256-3a  ld-elf/pr26256-3b
  s390-linux ...       LD REGRESSION: ld-elf/pr26256-3a  ld-elf/pr26256-3b
  score-elf ...        LD REGRESSION: ld-elf/pr26256-3a  ld-elf/pr26256-3b

(This is just a selection).

The cause appears to be an incorrect assumption about the start address of
the text section:

   regexp_diff match failure
   regexp "^  0x[a-f0-9]+ +020103 +.+$"
   line   "  0x00000020 02010000 03000000                   ........"
   FAIL: ld-elf/pr26256-3a

   regexp_diff match failure
   regexp "^  0x[a-f0-9]+ +020103 +.+$"
   aline   "  0x00000020 02010000 03000000                   ........"
   FAIL: ld-elf/pr26256-3b

Could you fix these please ?

Cheers
