undefined symbol: __clock_nanosleep_time64

nightly 2026-03-30 works normally.

Start by comparing the hexagon-unknown-linux-musl link command and undefined symbols between nightly 2026-03-30 and 2026-03-31. Investigate the target's rust-lld and hexagon-unknown-linux-musl-clang inputs, focusing on __stat_time64, __clock_gettime64, and __clock_nanosleep_time64. Done means the target links successfully on the newer nightly without these undefined-symbol errors.
