Yann E. MORIN" 43ca5b4095 config: add support for a second part of the generated choices
Some components have configuration options that can depend on
generic options, so they should go below those.

uClibc for example:
- has its own options (wchar...)
- uses the generic options (threads...)
- if linuxthreads chosen, offers two impls

So we need to be able to split the components options in 2,
one part that is above the generic options, and one part that
ends up below the generic options.

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.
