[patches] Cross testing

[Khem Raj <kraj@xxxxxxxxxx>]

Hi

Cross testing worked for me almost out of the box when I used localhost 
as my target.
Only problem I found was that the scripts/cross-test-ssh.sh does not 
have +x attribute
so it does not run as mentioned in its help.

To use this to run EGLIBC tests, invoke the tests as follows:

 $ make cross-test-wrapper='ABSPATH/cross-test-ssh.sh HOST' tests


however

$ make cross-test-wrapper='sh ABSPATH/cross-test-ssh.sh HOST' tests

worked.

So either we can change the attribute of the file in repository or make 
the above change.

While running it on a really remote target I needed to do couple of things

Actually testing expects to have same user on both machines. So either 
use NIS and passwordless ssh entry into target

or create an user with same name and then copy your .ssh/id_dsa.pub to 
target user home as .ssh/authorized_keys


But in the end it all worked.

I have created a script based on Jim's instructions to build eglibc 
toolchain. I have put it on
