the vector class symbols are only needed on the target. Don't inject
(or expect) them into the host binaries to avoid multi-device build
conflicts and ABI breakage

msm7x30: Mount all partitions in fstab

Android is missing shutdown logic for partitions mounted in init
We mounted the mtd partitions in init in kitkat because for some
reason they couldn't be mounted through fstab

Looks like this works now, so revert back to standard mount way.
