[Bug target/38988] Cannot build crtstuff.c with -mcmodel=large -fPIC -O2

Assuming you have solved crtstuff.c issue, will /usr/lib64/crt1.o
work with -Wl,--section-start,.text=0x110000000? Can you try
the latest binutils from CVS with

[hjl@gnu-6 pr38988]$ cat f.c
#include <stdio.h>

int
main ()
{
  printf ("hello\n");
  return 0;
}
[hjl@gnu-6 pr38988]$ gcc f.c -Wl,-Ttext-segment,0x110000000 -fpie -pie -g
[hjl@gnu-6 pr38988]$ gdb a.out

(gdb) r
Starting program: /export/home/hjl/bugs/gcc/pr38988/a.out 

Breakpoint 1, main () at f.c:6

(gdb) p $rip
$1 = (void (*)()) 0x110000708 <main+4>
(gdb) c
Continuing.
hello

Program exited normally.
(gdb) 

I added a new linker switch:

-Ttext-segment ADDRESS      Set address of text segment

It may work for you.
