static-pie: Skip the empty PT_LOAD segment at offset 0 [BZ #32763]
As shown in
https://sourceware.org/bugzilla/show_bug.cgi?id=25237
linker may generate an empty PT_LOAD segments at offset 0:
Elf file type is EXEC (Executable file)
Entry point 0x4000e8
There are 3 program headers, starting at offset 64
Program Headers:
Type Offset VirtAddr PhysAddr
FileSiz MemSiz Flags Align
LOAD 0x0000000000000000 0x0000000000400000 0x0000000000400000
0x00000000000000f0 0x00000000000000f0 R E 0x1000
LOAD 0x0000000000000000 0x0000000000410000 0x0000000000410000
0x0000000000000000 0x0000000000b5dce8 RW 0x10000
GNU_STACK 0x0000000000000000 0x0000000000000000 0x0000000000000000
0x0000000000000000 0x0000000000000000 RW 0x10
Section to Segment mapping:
Segment Sections...
00 .text
01 .bss
02
Skip the empty PT_LOAD segment at offset 0 to support such binaries.
This fixes BZ #32763.
