mescc: Update elf32-header for linux-4.17.
...
Previously, our binaries showed this
$ readelf -s scaffold/main.mes-out
There are 2 program headers, starting at offset 64
Program Headers:
Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align
LOAD 0x000000 0x01000000 0x01000000 0x0557c 0x0557c RWE 0x1
LOAD 0x000000 0x01000000 0x01000000 0x0557c 0x0557c RWE 0x1
Section to Segment mapping:
Segment Sections...
00 .text .data
01 .text .data
Linux-4.17 refuses to run this and says
Uhuuh, elf segment at 0000000001000000 requested but the memory is mapped already
Segmentation fault
* lib/x86-mes/elf32-header.hex2: Remove unused data program header.
