Enter the date of the snapshot you want to use in the form: YYYYMMDD
where YYYY is the 4-digit year, MM the 2-digit month and DD the 2-digit
day in the month.
Please note:
- glibc has snapshots done every monday, and only the last ten are kept.
- uClibc has daily snapshots, and only the last 30-or-so are kept.
So if you want to be able to re-build your toolchain later, you will
have to save your C library tarball by yourself.

help
Say 'Y' here if you want to have a ldd-like helper that
you can run on your build system, and that will (try to)
resolve shared libraries dependencies as if run on the
target.
Note that the cross-ldd helper is not a full replacement
for the native ldd. Please see the help, by running it
with '--help' for more explanations.
