@kcudnik Could you please take a look at the build failure? I think it might relate to sonic-net/sonic-sairedis#806

[kcudnik]

pysairedis_wrap.cpp: In function 'int SWIG_AsVal_double(PyObject*, double*)':
pysairedis_wrap.cpp:3474:33: error: conversion to 'double' from 'long int' may alter its value [-Werror=conversion]
     if (val) *val = PyInt_AsLong(obj);
                     ~~~~~~~~~~~~^~~~~
At global scope:
cc1plus: error: unrecognized command line option '-Wno-cast-function-type' [-Werror]

those are 2 errors, conversion and not recognized cast-function-type parameter, this is wired, since build is passing fine on sairedis repo, and on this build here is passing on mellanox and on broadcom - i just chcked brcm and mlnx builds, and it seems like it's not actually building since i dont see logs from sairedis build inside azure pipeline

seems like gcc version used in compiled sonic-buildimage is older than the one used in sonic sairedis

Attempt to fix this: sonic-net/sonic-sairedis#817
