Build VirtualBox for old version target, and newer version (7.0 and 7.1)

[TK50P]

Is your feature request related to a problem? Please describe.
Yes. building VirtualBox 5.0.40, it uses QT4. however, this script uses QT5, likely causing compability issues.
because VirtualBox 5.0 has no option like --with-qt5= and only available --with-qt4=
Even for VirtualBox 7.1 (Currently Beta), which will be released later, this option is also required to use QT6.
OpenSSL also causes it. (--with-openssl=)

Describe the solution you'd like
Please make an legacy/new scripts that Builds old VirtualBox.
Not only for 6.1, 6.0 and earlier even 4.x.

Describe alternatives you've considered
Making a section that will build QT4 or QT5.

Additional context
None.

Thank you for your report! It wouldn't be so hard to support qt4 and qt6 since it would be similar to supporting qt5. Let me handle this with the other issues soon.

Also, we have to update download link because the openssl link is dead.
