configure: Work around broken static pkg-config info for Ubuntu gnutls
Unfortunately Ubuntu's pkg-config information for gnutls is broken
for the static linking case, and outputs --libs options which the
compiler does not recognize. Work around this problem by testing
that the --cflags/--libs output will at least allow compilation
before enabling gnutls support.
