[3/3,AARCH64] ILP32: redirect stat syscall family to 64-bit handlers
Commit Message
__ASSUME_SUPPORT_64_BIT_TIME_TYPES and XSTAT_IS_XSTAT64 are enabled
to ensure that glibc creates stat{,fs} layouts identical to 64-bit
versions, and so we can redirect corresponding syscalls 64-bit handlers.
statfs() and fstatfs() are handled separately as aarch64 requires
non-standard argument passing.
* sysdeps/unix/sysv/linux/aarch64/bits/typesizes.h: enable
__ASSUME_SUPPORT_64_BIT_TIME_TYPES and XSTAT_IS_XSTAT64
* sysdeps/unix/sysv/linux/aarch64/ilp32/fstatfs64.c: handle
fstatfs() syscall
* sysdeps/unix/sysv/linux/aarch64/ilp32/statfs64.c: handle
statfs() syscall
