ltp: backport patch to fix compilation error for Skylake -march=x86-64-v3

When the input compiler enables AVX, stack realignment requirements
causes gcc to fail to omit %rbp use, due to which the test fails to
clobber %rbp in inline asm.  Disable AVX to build the test on x86_64 so
that the test continues working.
