libc/newlib: allow using CVS snapshots

Browse Source 
The newlib "team" rolls new releases about once a year (december).
This is quite a long time between releases, in case code was fixed.
So, allow user to use a CVS snapshot to benefit early from fixes
and enhancements to newlib.

The newlib "team" rolls new releases about once a year (december).
This is quite a long time between releases, in case code was fixed.
Saying 'Y' here will allow you to use the bleeding-edge code from
the CVS repository. This may or may not fix your issues, may or may
not build, may or may not crash your machine, may or may not withdraw
money from your bank account, may or may not date your girlfriend,
may or may not resurect Elvis... :-)
In a word: use the CVS snapshot at your own risk!

Enter the tag you want to use.
Leave empty to use the 'head' of the repository.
