Yeah, something like that. :-) Thanks! I knew something like that was 
needed, but I did not feel like writing it.

I took your snipped and adapted it slightly, to improve readability for 
common cases. E.g. if you call --with-extra-cflags="-DFOO -DBAR" it will 
store it as --with-extra-cflags='-DFOO -DBAR' rather than 
'--with-extra-cflags=-DFOO -DBAR'. They both evaluate to the same 
result, but the former is -- to me, at least, more easy to read and more 
likely to match what the user initially wrote.

This interception needs to happen early, in the configure wrapper.

I've tried to make this break with various evil combinations, but 
failed, so I think it's fairly robust. (And once again I really miss 
that I can't turn such adhoc testing into proper tests. :-( )

Here's a new webrev:
