mysql is(should be) disabled by default in the makefiles, so you have
to pass --with-mysql* arguments to explicitly enable mysql  in your
build.
if you don't need it, you can just omit the --with-mysql or set it to 'no'
I don't know much about OpenSuse, but for debian you have to
explicitly install the php5-mysql package, without that, you have no
mysql related module in the module list generated by php -m.

the windows build however seems interesting, I've just downloaded the
php-5.3.8-nts-Win32-VC9-x86.zip package, and it shows the mysqlnd in
the module list, albeit I don't see that explicitly added in the
configure line:
Configure Command =3D> cscript /nologo configure.js
"--enable-snapshot-build" "--enable-debug-pack" "--disable-zts"
"--disable-isapi" "--disable-nsapi" "--without-mssql"
"--without-pdo-mssql" "--without-pi3web"
"--with-pdo-oci=3DD:\php-sdk\oracle\instantclient10\sdk,shared"
"--with-oci8=3DD:\php-sdk\oracle\instantclient10\sdk,shared"
"--with-oci8-11g=3DD:\php-sdk\oracle\instantclient11\sdk,shared"
"--with-enchant=3Dshared" "--enable-object-out-dir=3D../obj/"
"--enable-com-dotnet" "--with-mcrypt=3Dstatic"
"--disable-static-analyze"

maybe Pierre can elaborate why is that.
