Work around abs rela relocations issue (for now):
$ readelf -r compat_linux
...
Relocation section '.rela.data' at offset 0x37270 contains 537 entries:
Offset Info Type Sym. Value Sym. Name + Addend
...
000000000040 000000000001 R_X86_64_64 0
000000000048 000000000001 R_X86_64_64 0
...
$ objdump -r compat_linux
...
RELOCATION RECORDS FOR [.data]:
OFFSET TYPE VALUE
...
0000000000000040 R_X86_64_64 *ABS*
0000000000000048 R_X86_64_64 *ABS*
...
Since those have symidx == 0, and the 0 symbol table entry is special,
treat them as SHN_ABS.
Change ENOENT -> ENOEXEC to avoid confusion (like other linking errors),
and add some debugging when that happens.
