PHP 7.3 and 7.4 fail to compile on Debian 9.13 with error checking SSSE3 CPU feature


I’m working on updating a system from using PHP 7.2 to PHP 7.4, but I ran into a compiling error that I haven’t seen before and I’m not entirely understanding why it isn’t working.

In file included from /home/derek/php-7.4.11/ext/standard/base64.c:369:
/home/derek/php-7.4.11/Zend/zend_cpuinfo.h:143:9: error: invalid cpu feature string for builtin
        return __builtin_cpu_supports("ssse3");
               ^                      ~~~~~~~
1 error generated.
Makefile:1286: recipe for target 'ext/standard/base64.lo' failed
make: *** (ext/standard/base64.lo) Error 1
make: *** Waiting for unfinished jobs....

And this is the configure command I used:

./configure –with-openssl –with-system-ciphers –without-sqlite3
–enable-exif –enable-fpm –with-fpm-systemd –with-mysqli –with-sodium –enable-mbstring –with-pdo-mysql –without-pdo-sqlite –with-config-file-path=/etc/php –with-libdir=/lib/x86_64-linux-gnu

It doesn’t report any issues with configure, only when it comes to compile. configure does correctly identify that ssse3 is not supported on the system.
