[poky] gnutls-2.12.14-r3.1 - strange rpm names yocto

[Foinel]

Looking at gnutls-2.12.14/libextra/COPYING it says just GPLv3, so no
dual licensing or exceptions of any kind for these extra libraries.
Can anyone explain why in
meta/conf/distro/include/default-distrovars.inc it says:

# This is a list of packages that are used by the build system to
build the distribution, they are not
# directly part of the distribution..
HOSTTOOLS_WHITELIST_GPLv3 ?= ""
WHITELIST_GPLv3 ?= "less"
LGPLv2_WHITELIST_GPLv3 ?= "libassuan gnutls libtasn1 libidn libgcc gcc-runtime"

Does this mean gnutls is some sort of a host tool?
Because of this fact (gnutls being in LGPLv2_WHITELIST_GPLv3), then
the restriction to avoid GPLv3 packages seems not applicable to
gnutls. Does anyone know if gnutls is a special case in what concerns
the licensing?

Thanks.
