jenkins build this please

There are two different ways to fix the raspberry pi build issue

• remove storage/linux directory at cmake/treedata/rbpi/subdirs.txt
• surround core_add_library(...) at xbmc/storage/linux/CMakeLists.txt with if(NOT ENABLE_STATIC_LIBS OR DBUS_FOUND OR UDEV_FOUND)

Just wondering, raspberry pi does not have udev?

[MartijnKaijser]

@popcornmix?

[popcornmix]

Pi does use udev (it is just standard linux).
I believe udev isn't enabled for jenkins builds purely due to limitations of the build system when cross compiling. @wsnipex may know more about this.

[wsnipex]

udev is provided by systemd these days and we don't have that (nor old standalone udev) in depends.
It only works on x86 because we "cheat" too much there and allow the use of system libs.

I'm a bit puzzled about dbus though. We have it in depends, but it is never built. I've tried to track down if that was removed in the past, but can't find a ref that it was actually ever built...

@pkerling this needs a rebase

[yol]

Done. Can we merge this then? Pi build stuff is peculiar, but not really related to this PR.

[popcornmix]

If nothing has changed (i.e. Jenkins builds for Pi successfully without udev enabled) then no objections here.
