Dear Community,

> This patch introduces new recipe - namely 'glibc-tests', which
> builds and installs time related (to check if Y2038 support works)
> glibc test suite to OE/Yocto built image.
> 
> It reuses code from already available 'glibc-testsuite' recipe,
> which is run with 'bitbake glibc-testsuite -c check' and uses qemu
> to execute remotely (via SSH) tests on some emulated machine.
> 
> This recipe installs time related glibc tests on some rootfs image.
> Afterwards, those tests can be executed on the real hardware, to
> facilitate validation of it with Y2038 problem compliance.
> 
> To test time related subset - one needs to call:
> ptest-runner glibc-tests
> then change the date after Y2038 threshold for 32 bit systems:
> date -s "20 JAN 2038 18:00:00"
> and then run ptest-runner again.

> To facilitate debugging, source files are provided by default with
