kernel.bbclass: enable a link for external module building

Even though the kernel-dev package provides the required support for
building external kernel modules on the target, some commonly used scripts
and utilities fail as they are not finding the kernel module build support
files at the desired location.

Create the /lib/modules/<kernel-version>/build link on target pointing to
the sources provided by the kernel-dev package, to fix the issue.

meta-environment: Deal with machines which change TARGET_OS

Some machines change TARGET_OS, cross-canadian resets this which
is not what we want in this specific case. This fixes spe toolchains
for example.

cross-canadian: Disable the packagedata stamp-extra-info

Similarly to native/cross disable this since otherwise the packagedata
can be marked as machine specific and if you switch machines
which share an arciteture, you'll get toolchain overlapping files
errors.

pseudo*.bb: update to pseudo 1.6.2

pseudo 1.6.2 fixes problems with 64-bit inodes and some underlying issues
involving file renames that could occasionally cause very strange behaviors
files being deleted, linked, or renamed, mostly observed as strange
recovery if an inode got reused.

LTP - realtime tests - fix bad PI mutex conditionals

The priority inheritance tests for mutexes used conditional variables
which were non-existent.  Changed the conditional clauses to use the
variables which were actually generated by LTP autoconf for that purpose.

package.bbclass: Reverse runtime symlinks should be tied to package generation

In case a package is not generated (is empty and does not has allow
empty flag set) the package data regarding reverse runtime dependency
shouldn't be done.

This were causing a false-positive in the meta-fsl-arm layer, when
building mesa, as:
