libatomics-ops: patch source code for x32
This Fixes bug: [YOCTO #1418]
Remove the `q' suffix on x86-64 atomic instructions.
We don't need the `q' suffix on x86_64 atomic instructions for AO_t,
which is defined as "unsigned long". "unsigned long" is 32bit for x32
and 64bit for x86-64. The register operand in x86-64 atomic instructions
is sufficient to properly determine the register size.
