<pre>
When running an LLVM build on Debian/sparc64, several `compiler-rt` tests `FAIL` with linker errors. Although the primary linker is `ld.bfd` 2.42.50.20240625, some tests are specificially run with `ld.lld`. Admittedly this is currenty `lld` 16.0.6, AFAICS most if not all of the issues remain:
```
ld.lld: error: unknown emulation: elf32_sparc
```
```
ld.lld: error: /lib/sparc64-linux-gnu/Scrt1.o:(function _start: .text+0x1c): unknown relocation (82) against symbol main
ld.lld: error: /lib/sparc64-linux-gnu/Scrt1.o:(function _start: .text+0x20): unknown relocation (83) against symbol main
ld.lld: error: /lib/sparc64-linux-gnu/Scrt1.o:(function _start: .text+0x24): unknown relocation (84) against symbol main
```
which is
```
#define R_SPARC_GOTDATA_OP_HIX22 82
#define R_SPARC_GOTDATA_OP_LOX10 83
#define R_SPARC_GOTDATA_OP 84
```
```
ld.lld: error: /tmp/lit-tmp-gq6t5qs1/coverage-linkage-35e2a3.o:(__llvm_prf_data+0x10): unknown relocation (46) against symbol
```
which is
```
#define R_SPARC_DISP64 46 /* PC relative 64 bit */
```
```
ld.lld: error: relocation R_SPARC_64 cannot be used against local symbol; recompile with -fPIC
```
I'm still looking how to properly disable use of `-fuse-lld` on this target; maybe it should be done in `compiler-rt` for now.
