[gdb/testsuite] Fix gdb.arch/amd64-tailcall-self.S

Browse Source 
The test-case gdb.arch/amd64-tailcall-self.exp fails here:
...
if ![runto b] {
    return -1
}
...
like:
...
(gdb) file build/gdb/testsuite/outputs/gdb.arch/amd64-tailcall-self/\
  amd64-tailcall-self
Reading symbols from build/gdb/testsuite/outputs/gdb.arch/\
  amd64-tailcall-self/amd64-tailcall-self...
Dwarf Error: Cannot find DIE at 0x1f5 referenced from DIE at 0x107 [in \
  module build/gdb/testsuite/outputs/gdb.arch/amd64-tailcall-self/\
  amd64-tailcall-self]
...

The problem is that in amd64-tailcall-self.S, CU-relative references are
assigned .debug_info section relative values.  [ This is similar to the
problem fixed by "Fix gdb.arch/amd64-entry-value-paramref.S". ]

Fix this by assigning CU-relative references instead.

Tested on x86_64-linux.
