When cross-compiling the perf tool for ARM64, `perf help` may crash with the following assertion failure: help.c:122: exclude_cmds: Assertion `cmds->names[ci] == NULL' failed. This happens when the perf binary is not named exactly "perf" or when multiple "perf-*" binaries exist in the same directory. In such cases, the `excludes` command list can be empty, which leads to the final assertion in exclude_cmds() being triggered. Add a simple guard at the beginning of exclude_cmds() to return early if excludes->cnt is zero, preventing the crash.
