[PATCH][gold] Fix printing the address of a relaxed section in the map file.

[Igor Kudrin <ikudrin at accesssoftek dot com>]

Hi,

I've noticed that gold might print an invalid value (-1ULL) as
the address for a relaxed section. For example:

$ cat > test.s << EOF
.globl _start, foo

.section ".text.start", "ax"
_start:
    bl foo

.section ".text.hole", "ax"
    .space 0x4000000

.section ".text.foo", "ax"
foo:
    b _start
EOF
$ arm-none-eabi-as test.s -o test.o
$ ./gold-master test.o -o test.out -Map test.map
$ sed -n '/^.text/,/^$/p' test.map
.text           0x00008074  0x4000018
 .text          0x00008074        0x0 test.o
 .text.start    0xffffffffffffffff        0x4 test.o
                0x00008074                _start
 .text.hole     0x00008080  0x4000000 test.o
 .text.foo      0xffffffffffffffff        0x4 test.o
                0x04008080                foo

Here is the patch for the issue.

Best regards,
Igor Kudrin
