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.

(From OE-Core rev: daaaeb1bd1467a2bed75722ce3ff35be970402e0)
