[patch, libfortran] PR32235 incorrectly position text file after backspace

[Jerry DeLisle]

:ADDPATCH fortran:

The attached patch fixes this bug by moving the code that tests for the end of 
file condition from st_read, back to next_record_r.  I have regression tested 
this on x86-64-gnu-linux.

I need someone (HJ or Richard?) to test this with the SPEC testsuite to make 
sure we do not regress there. (The patch is against libgfortran/io/transfer.c)

If it passes SPEC as well, OK for trunk?

Test case included.

Regards,

Jerry
