    configury: Fix up --enable-link-serialization support

    Eric reported that the --enable-link-serialization changes seemed to
    cause the binaries to be always relinked, for example from the
    gcc/ directory of the build tree:
    make
    [relink of gnat1, brig1, cc1plus, d21, f951, go1, lto1, ...]
    make
    [relink of gnat1, brig1, cc1plus, d21, f951, go1, lto1, ...]
    Furthermore as reported in PR, it can cause problems during make install
    where make install rebuilds the binaries again.

    The problem is that for make .PHONY targets are just
    "rebuilt" always, so it is very much undesirable for the cc1plus$(exeext)
    etc. dependencies to include .PHONY targets, but I was using
    them - cc1plus.prev which would depend on some *.serial and
    e.g. cc1.serial depending on c and c depending on cc1$(exeext).

    The following patch rewrites this so that *.serial and *.prev aren't
    .PHONY targets, but instead just make variables.

    I was worried that the order in which the language makefile fragments are
    included (which is quite random, what order we get from the filesystem
    matching */config-lang.in) would be a problem but it seems to work fine
    - as it uses make = rather than := variables, later definitions are just
    fine for earlier uses as long as the uses aren't needed during the
    makefile parsing, but only in the dependencies of make targets and in
    their commands.

            * configure.ac: In SERIAL_LIST use lang words without .serial
            suffix.  Change $lang.prev from a target to variable and instead
            of depending on *.serial expand to the *.serial variable if
            the word is in the SERIAL_LIST at all, otherwise to nothing.
