Description:
------------
Compilation on Ubuntu 14.04 i386 ends with failure in asm code.

I don't have any builds between alpha4 and beta2, but alpha4 did succeed to build in the same environment.

I guess a similar patch to https://bugs.php.net/patch-display.php?bug_id=69896&patch=disable-asm-for-gcc-4.8&revision=latest

should be applied here as well.

Test script:
---------------
Just compile PHP 7.3.0beta2

Expected result:
----------------
Build to succeed.

Actual result:
--------------
In file included from /<<PKGBUILDDIR>>/Zend/zend.h:335:0,
                 from /<<PKGBUILDDIR>>/Zend/zend_execute.c:26:
/<<PKGBUILDDIR>>/Zend/zend_vm_execute.h: In function ‘ZEND_ADD_SPEC_CONST_CONST_HANDLER’:
/<<PKGBUILDDIR>>/Zend/zend_operators.h:575:2: error: ‘asm’ operand has impossible constraints
  __asm__ goto(
