The most confusing part of the %bcond is the definition itself. The rest
is fine IMO. Therefore, I somehow don't understand why would you like to
replace:
```
%if %{with ssl}
BuildRequires: openssl-devel
%endif
```
by
```
%if %{use ssl}
BuildRequires: openssl-devel
%endif
```
Also I don't understand, why there is exposed some underscore macro,
such as `make test %{?_use_ssl:-DSSL}`. Shouldn't the underscore macro
be just implementation detail? For `%bcond`s, the `_with` macros are
discouraged, so why would you encourage them?
