[PATCH 1/3] tst: Extend cross-test-ssh.sh to specify if target date can be altered

[Lukasz Majewski]

Dear Community,

> This code adds new flag - '--allow-time-setting' to cross-test-ssh.sh
> script to indicate if it is allowed to alter the date on the system
> on which tests are executed. This change is supposed to be used with
> test systems, which use virtual machines for testing.
> 
> The GLIBC_TEST_ALLOW_TIME_SETTING env variable is exported to the
> remote environment on which the eligible test is run and brings no
> functional change when it is not.

Gentle ping on this patch. It provides support for setting time in the
VM target on which glibc tests are executed (for example armv7a).
