This reverts commit8c8510ab27. The revert is not perfect because the commit included a bug fix for _dl_sysdep_start with an empty argv, introduced in commit2d47fa6862("Linux: Remove DL_FIND_ARG_COMPONENTS"), and this bug fix is kept. The revert is necessary because the reverted commit introduced an early memset call on aarch64, which leads to crash due to lack of TCB initialization.
