That does not mean anything really. Without parameters, configure has to 
assume the default native toolchain, default import and installation paths, 
default compilation parameters, default features, etc are in use. Thus, 
practically any VLC build requires custom parameters, even when building 
natively, and that's hardly avoidable.

However, if some parameters (typically compiler/toolchain related) is required 
for the entire system (e.g. OS distro) or the whole binary VLC package (e.g. 
including contrib), then it clearly does not belong in configure. It belongs 
in the packaging system that sits on top of it and runs it.

Clearly the MacOS port is abusing the configure script in that respect. And 
that causes a lot of avoidable code churn.

Conversely, if some parameter applies only to a one module, or any subset of 
the VLC source tree, then it should be set in the Makefiles, as far as 
possible. In many such cases but not always, some detection code in configure 
is unavoidable (for instance calling pkg-config).
