Sync Zend/*_i386_sysv_elf_gas.S with upstream (#15788)

This is a sync with upstream already fixed in early 2024 which fixes
64-bit builds on 32-bit hosts. PHP's bundled config.guess sets the
host_alias, for example, on Solaris systems to 64-bit if the compiler
supports it even though the architecture is actually 32-bit. These
assembly files resolve this situation in a build-system-agnostic way by
including the architecture file that is supported by the compiler.
