This patch consolidates all Linux truncate implementation on
sysdeps/unix/sysv/linux/truncate{64}.c. It is based on
{INTERNAL,INLINE}_SYSCALL patch [1] to simplify the syscall
construction.
General idea is to build ftruncate iff __OFF_T_MATCHES_OFF64_T is not
defined, otherwise ftruncate64 will be build and ftruncate will be an
alias. The fallocate will use old compat syscall and pass 32-bit off_t
argument, while fallocate64 will handle the correct off64_t passing using
__ALIGNMENT_ARG and SYSCALL_LL64 macros.
Tested on x86_64, i386, aarch64, and armhf.
* sysdeps/unix/sysv/linux/arm/truncate64.c: Remove file.
* sysdeps/unix/sysv/linux/generic/wordsize-32/truncate.c: Likewise.
* sysdeps/sysv/linux/generic/wordsize-32/truncate64.c: Likewise.
* sysdeps/unix/sysv/linux/mips/mips32/truncate64.c: Likewise.
* sysdeps/unix/sysv/linux/mips/mips64/truncate64.c: Likewise.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/truncate64.c: Likewise.
* sysdeps/unix/sysv/linux/wordsize-64/truncate64.c: Likewise.
* sysdeps/unix/sysv/linux/truncate.c: New file.
* sysdeps/unix/sysv/linux/truncate64.c (truncate64): Use
INLINE_SYSCALL_CALL, __ALIGNMENT_ARG and SYSCALL_LL64 macros.
* sysdeps/unix/sysv/linux/mips/mips64/syscalls.list (truncate):
Remove.
* sysdeps/unix/sysv/linux/wordsize-64/syscalls.list (truncate):
Likewise.
