Bug with PHP-GMP and PHP 5.6?

I have a server with PHP 7.3 and 5.6 installed:

# grep ^php[12]_release /usr/local/directadmin/custombuild/options.conf

I also have gmp enabled:

# grep ^gmp /usr/local/directadmin/custombuild/php_extensions.conf

When I try to run ./build update_versions, this is the output I get:

# ./build update_versions
Updating PHP-GMP 5.6
Cannot build xmlrpc, because you do not have it set in php_extensions.conf file.

Sure enough, xmprpc is not enabled:

# grep ^xml /usr/local/directadmin/custombuild/php_extensions.conf

If I set xmlrpc=yes, and re-run ./build update_versions, I get xmlrpc, but still no GMP.

Looks like it's line 28705 that makes the call to doPHPXmlrpc instead of doPHPGmp. Unsure if this is related to any specific PHP version, but I haven't seen the same issue on servers with 7.2 and 7.3 that I can remember.

# ./build version
2.0.0 (rev: 2517)

If I change this line 28705 to call the doPHPGmp function instead, it is successfully built for PHP 7.3.19, but for PHP 5.6.40 it fails with the following error:

Looks like gmp support shouldn't be an issue with PHP 5.6 in general, so I'm not sure what's going on here.

I have libgmp-dev installed, that contains the gmp.h file:

# dpkg -L libgmp-dev | grep gmp.h$
