Comment (by danadam):

 In my case (Debian Testing) I have:
 {{{
 /usr/bin/ld: cannot find -lunistring
 collect2: error: ld returned 1 exit status
 ERROR: gnutls not found using pkg-config
 }}}
 In `gnutls.pc` there is:
 {{{
 Libs: -L${libdir} -lgnutls
 Libs.private:    -pthread   -lgmp -lunistring -latomic
 }}}
 The `--pkg-config-flags="--static"` option to `configure` makes it use
 "Libs.private" line, so it tries to link with unistring. The problem is
 that "libgnutls28-dev" does not depend on "libunistring-dev".

 I removed the option and if fixed the issue. I suspect that manually
 installing libunistring-dev would also fix it, although I found this
 regarding static linking of gnutls:

   Note that static linking applications with gnutls is not something
 supported. gnutls relies on library constructors and destructors which are
 not loaded when linking statically.
