ci: use Mold linker for asan-lsan-ubsan-integer-no-depends-usdt workflow
What changed, and why it matters
This commit changes a single Bitcoin Core continuous-integration (CI) script so that one automated testing job uses the Mold linker instead of the default system linker. It adds the 'mold' package to the CI container and tells the build to use it. There is no change to the Bitcoin Core software that users run, no bug fix, and no security relevance.
No security action needed. This is a routine CI configuration change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff modifies ci/test/00_setup_env_native_asan.sh, the environment setup for the native AddressSanitizer/LeakSanitizer/UBSan/integer-no-depends/USDT CI workflow. It installs the ‘mold’ package and passes -DCMAKE_EXE_LINKER_FLAGS=’-fuse-ld=mold’ to the CMake configuration. This is purely an infrastructure/CI tooling change intended to switch linkers for that specific build job.
