[Bug libc/17836] New: -pg -pie doesn't work on x86-64


https://sourceware.org/bugzilla/show_bug.cgi?id=17836

            Bug ID: 17836
           Summary: -pg -pie doesn't work on x86-64
           Product: glibc
           Version: 2.21
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: hjl.tools at gmail dot com
                CC: drepper.fsp at gmail dot com

On x86-64, I got

[hjl@gnu-tools-1 tmp]$ cat x.c
#include <stdio.h>

int
main ()
{
  printf ("hello\n");
  return 0;
}
[hjl@gnu-tools-1 tmp]$ cat y.c
int
main ()
{
  return 0;
}
[hjl@gnu-tools-1 tmp]$ gcc -pie -pg y.c
/usr/local/bin/ld:
/usr/lib/gcc/x86_64-redhat-linux/4.8.3/../../../../lib64/gcrt1.o: relocation
R_X86_64_32S against `__libc_csu_fini' can not be used when making a shared
object; recompile with -fPIC
/usr/lib/gcc/x86_64-redhat-linux/4.8.3/../../../../lib64/gcrt1.o: error adding
symbols: Bad value
collect2: error: ld returned 1 exit status
[hjl@gnu-tools-1 tmp]$ 

The problem is gcrt1 isn't compiled with -fPIC.  Should we compile it with
-fPIC?
