LOG: [compiler-rt][test] Disable lld tests on SPARC (#100533)

As detailed in Issue #100320, a considerable number of tests that
explicitly use `-fuse-ld=lld` `FAIL` on Linux/sparc64 due to several
`lld` limitations (no 32-bit SPARC support, lack of support for various
relocations, ...).

To reduce the noise, this patch disables `COMPILER_RT_HAS_LLD` on SPARC
wholesale.

Tested on `sparc64-unknown-linux-gnu`.
