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.

     7 Attached is a patch to add __attribute__ ((noinline)) to
     8 call_gmon_start.
     9 
    10 Without this patch, the sec script that processed initfini.s removes a
    11 part of inlined call_gmon_start, causing undefined label errors.
    12 
    13 This patch solves the problem by forcing gcc not to inline
    14 call_gmon_start with __attribute__ ((noinline)).
    15 
    16 Tested by building for arm-none-lixux-gnueabi.  OK to apply?
