[ELF] Support some absolute/PC-relative relocation types for REL format
ctfconvert seems to use REL-format `.rel.SUNW_dof` for 32-bit architectures.
```
Binary file usr/ports/lang/perl5.32/work/perl-5.32.1/dtrace_mini.o matches
[alfredo.junior@dell-a ~/tmp/llvm-bug]$ readelf -r dtrace_mini.o
Relocation section (.rel.SUNW_dof):
r_offset r_info r_type st_value st_name
00000184 0000281a R_PPC_REL32 00000000 $dtrace1772974259.Perl_dtrace_probe_load
```
Support R_PPC_REL32 to fix `ld.lld: error: drti.c:(.SUNW_dof+0x4E4): internal linker error: cannot read addend for relocation R_PPC_REL32`.
While here, add some common relocation types for AArch64, PPC, and PPC64.
We perform minimum tests.
