    bootstrap: Fix some windows issues [PR 98300]

    When breaking out the sample server from the gcc/cp directory, it lost
    its check for mmap, and the sample resolver just assumed it was there.
    Fixed thusly.  The non-mapping paths in module.cc weren't (recently)
    excercised, and led to a signedness warning.  Finally I'd missed
    c++tools's config.h.in in the gcc_update script.  There I took the
    opportunity of adding a 'tools' segment of the dependency lists.
