Joseph Myers df34134284 Disable 64-bit atomics for MIPS n32.
This patch disables use of 64-bit atomics for MIPS n32 to fix the
problems with unaligned semaphores.

Before 64-bit atomics are used for anything for which such alignment
issues do not arise, and before the addition of any new ILP32 ports
with 64-bit semaphores for which the ABI can be set to have the
greater alignment (AARCH64?), a better approach will need to be
established that allows architectures to declare their 64-bit atomics
availability accurately, without doing so causing inappropriate use of
such atomics on unaligned semaphores.

Tested for MIPS n32 that this fixes the nptl/tst-sem3 failure.

	(__HAVE_64B_ATOMICS): Define to 0.
