[Ltib] tslib is needed by DirectFB...

[Peter Barada]

Stuart,

I've stumbled across a problem with DirectFB - if you build it as part
of LTIB from scratch you end up with rootfs/usr/lib/inputdrivers having:

address@hidden:~/work/logic/eps_svn/software/products/linux/LTIB/trunk/ltib-3.0-nand$
ls rootfs/usr/lib/directfb-1.1-0/inputdrivers/
libdirectfb_keyboard.so  libdirectfb_linux_input.so

But if you "./tlib -p DirectFB -m scbuild && ./ltib -p DirectFB -m
scdeploy" to rebuild/deploy DirectFB, it will then build/install the
tslib DirectFB input driver:

address@hidden:~/work/logic/eps_svn/software/products/linux/LTIB/trunk/ltib-3.0-nand$
ls rootfs/usr/lib/directfb-1.1-0/inputdrivers/
libdirectfb_keyboard.so  libdirectfb_linux_input.so  libdirectfb_tslib.so


This is due to DirectFB being built before tslib - and once tslib is
installed, DirectFB's configure will find it (if PKG_DIRECTFB__WANT_TS
is enabled).  In the initial configure log from DirectFB you'll find:

checking which gfxdrivers should be built... checking which inputdrivers
should be built... tslib keyboard linuxinput
checking linux/input.h usability... yes
checking linux/input.h presence... yes
checking for linux/input.h... yes
checking for struct input_absinfo in linux/input.h... yes
checking for arm-linux-pkg-config... no

checking pkg-config is at least version 0.9.0... yes
checking for TSLIB... no
configure: WARNING: *** no tslib -- tslib driver will not be built.


Following is a patch to config/userspace/pkg_map that looks to fix the
issue (just hoits PKG_TSLIB to before PKG_DIRECTFB):
