Subject: [PATCH] [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`.
(cherry picked from commit 33a50e0eaa80cf3db1b944762db9a37a06f3ac32)
