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

[Andrei Gherzan]

Hello guys,

I've been plying along with yocto lately and managed to understand at a 
decent level it's work-flow and components.

Today wanted to complete an image-core-minimal for arm using packages 
that are not GPLv3 using (found in manual):
#EXTRA_IMAGE_FEATURES = "debug-tweaks"
INCOMPATIBLE_LICENSE = "GPLv3"

Further more i wanted to compile gnutls and i think that i came across a 
bug. In the bb file (poky/meta/recipes-support/gnutls/gnutls_2.12.14.bb) 
the rules for pakages are:
PACKAGES =+ "${PN}-openssl ${PN}-extra ${PN}-bin ${PN}-xx"

FILES_${PN} = "${libdir}/libgnutls.so.*"
FILES_${PN}-bin = "${bindir}/gnutls-serv \
                    ${bindir}/gnutls-cli \
                    ${bindir}/srptool \
                    ${bindir}/psktool \
                    ${bindir}/p11tool \
                    ${bindir}/certtool \
                    ${bindir}/gnutls-srpcrypt"

FILES_${PN}-dev += "${bindir}/*-config ${bindir}/gnutls-cli-debug"
FILES_${PN}-extra = "${libdir}/libgnutls-extra.so.*"
FILES_${PN}-openssl = "${libdir}/libgnutls-openssl.so.*"
FILES_${PN}-xx = "${libdir}/libgnutlsxx.so.*"

So the rpms should be named gnutls-dev, gnutls-bin etc etc.
Well... this is not true cause in the 
tmp/work/armv5te-poky-linux-gnueabi/gnutls-2.12.14-r3.1/deploy-rpms

More infos: I'm using multithreading building and my last commit in poky 
is "commit af7fbd6083f4b5f1770e58fe0a2262951037c176."

I just cannot understand how these names are built. More, what are 
libgnutls-openssl27 and libgnutlsxx27?
