[BZ #758] * sysdeps/unix/sysv/linux/mips/configure.in (asm-unistd.h): Only preprocess <asm/unistd.h> if it defines ABI-prefixed syscall names like __NR_N32_open. Just include <asm/unistd.h> otherwise. * sysdeps/unix/sysv/linux/mips/configure: Regenerate. * sysdeps/unix/sysv/linux/mips/mips32/kern64/sysdep.h: Delete * sysdeps/unix/sysv/linux/mips/mips64/n32/sysdep.h (SYS_ify): Use the standard __NR prefix. * sysdeps/unix/sysv/linux/mips/mips64/n64/sysdep.h (SYS_ify): Likewise. * sysdeps/unix/sysv/linux/mips/Makefile (syscall-%.h): Rework so that the output file is compatible with both pre-2.6 and 2.6 kernel headers. Extract separate syscall lists for each ABI.
