+ mips: Remove duplicate macro definitions
+
+ The INLINE_SYSCALL, INTERNAL_SYSCALL*, and internal_syscall* macros
+ are defined for MIPS in both libc/sysdeps/linux/mips/sysdep.h and
+ libc/sysdeps/linux/mips/bits/syscalls.h. The macros are the same
+ in both cases except that syscalls.h defines internal_syscalls[567]
+ the same for N32 and N64 ABIs and has a different definition for O32.
+ I believe that is correct. The sysdep.h header uses the O32 versions
+ for N32 and has different definitions for N64. I think that is wrong
+ and that N32 and N64 should share the same definition (modulo the
+ type 'long' vs. 'long long' for the arguments. This setup (from
+ sysdep.h) now agrees with what glibc has.
+
+ I am not positive about which header (sysdep.h vs syscalls.h) is
+ really the right one to have these definitions in but using sysdep.h
+ seems to work for all my builds.
