Patch to www/curl for libidn

[Alistair Crooks <agc%pkgsrc.org@localhost>]

Hi,

Does anyone have any problem with the attached patch to make libidn
support in curl switchable - default is on, still, but allows us to
build curl without libidn support.  One of the reasons for this is
that libidn is:

LICENSE=        gnu-gpl-v3 AND gnu-lgpl-v2.1

Thanks,
Alistair
