Support files which's length is larger than 4GB:
https://www.opengroup.org/platform/lfs.html
Note: the protected and kernel mode on 32bit platform can't exceed
the 4GB limitation since the auto generated proxy and stub still
cut 64bit to 32bit value. Please check tools/mksyscall.c for more
information.
