New Comment:
you may try to add -mavx to your configuration...
and, you are trying compile with -march=core-avx2 which is not the same as -march=native which you
are debugging
thanks

It seems that AVX support has been introduced with commit
5c05870[1]. @laruence, could you please have a look at this
issue?

Description:
------------
Test source compile of PHP 7.3.0alpha1 results in failure at opcache section but only on Intel Xeon
Gold Skylake server with CentOS 7.5 64bit (running in Ubuntu 18.04 LTS with LXD 3.1 based CentOS 7.5
container https://github.com/centminmod/centminmod-lxd).
PHP 7.3.0alpha + Zend Opcache successfully compiles on Xeon E3-1270v1 Sandybridge system though.
Both Xeon Gold Skylake and Xeon E3-1270v1 systems using CentOS 7.5 GCC 4.8.5

Expected result:
----------------
expected it to compile successfully like it does with PHP 7.2.6 and 7.3.0alpha1 on non-skylake cpus
i.e. Xeon E3-1270v1 Sandybridge compiles fine
