H.J. Lu 596130591a 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.
