linux-tbs-drivers: update to linux-tbs-drivers-130429

this is a dirty workaround, because it seems like tbs can't do it right. again

in linux tbs driver changelog I see:

2. XXXXXX Linux Driver is updated to v130429, which has below updating
* Further improve Linux kernel 3.9.x compatibility.

which is, in fact, not true, after quick diff I realized
that they changed exactly nothing.

next time tbs should do their job, instead of announcing support for 'kernel xxx'
why would we support this driver in the future ? it's not our job to fix broken drivers now and then.
linux: update dvbsky patch
projects/*/linux/linux.*.conf: sync kernel configs
linux-tbs-drivers: don't build sh_mobile_csi2
Put libthread_db.so into the correct location for gdb

Otherwise we get:

    warning: Unable to find libthread_db matching inferior's thread library, thread debugging will not be available.
