Don't bother to define the symbols empty, just don't use them.
That makes the intent a little more clear.
Remove the unused HAVE_ARCH_STRUCT_FLOCK64 define and merge the
32-bit mips struct flock into the generic one.
Add a new __ARCH_FLOCK_EXTRA_SYSID macro following the style of
__ARCH_FLOCK_PAD to avoid having a separate definition just for
one architecture.

Being late to this, but this breaks the perf build for me using a MIPS
toolchain with the following:

Error 1
the kernel headers are set to 4.1.31 which is arguably old but
toolchains using newer kernel headers do not fare much better either
unfortunately as I tried a toolchain with kernel headers 4.9.x.
I will start doing more regular MIPS builds of the perf tools since that
seems to escape our testing.
Thanks!
