Linux: Use system call tables during build
Use <arch-syscall.h> instead of <asm/unistd.h> to obtain the system call numbers. A few direct includes of <asm/unistd.h> need to be removed (if the system call numbers are already provided indirectly by <sysdep.h>) or replaced with <sys/syscall.h>. Current Linux headers for alpha define the required system call names, so most of the _NR_* hacks are no longer needed. For the 32-bit arm architecture, eliminate the INTERNAL_SYSCALL_ARM macro, now that we have regular system call names for cacheflush and set_tls. There are more such cleanup opportunities for other architectures, but these cleanups are required to avoid macro redefinition errors during the build. For ia64, it is desirable to use <asm/break.h> directly to obtain the break number for system calls (which is not a system call number itself). This requires replacing __BREAK_SYSCALL with __IA64_BREAK_SYSCALL because the former is defined as an alias in <asm/unistd.h>, but not in <asm/break.h>.
