more external libraries converted to gbuild

[Matúš Kukan]

Hi,

I've done 7 more libraries.
http://cgit.freedesktop.org/libreoffice/core/commit/?id=707194e7b9263a33508905438281090bd201e34d
and before.

They had makefile.mk in the sources, so that file could be removed if
newer versions are not going to be used in libreoffice-3-6.

I have ignored:
.IF "$(COM)"=="GCC"
CFLAGSCXX+=-frtti
.ENDIF
We don't use it in gbuild. Is it needed ?

This may be unpopular change but I hope everything will be fine :-)

Btw: Now the tarballs are downloaded only when we don't use system
versions (I hope).

Thanks,
Matus
