Move the tools wrapper choice selection down to the companion libraries sub-menu, to avoid the user going back and forth in the menu.

gcc 4.3.0 and above requires both GMP and MPFR to build some frontends,
|
|
and some other components can use them as well.

These will be automatically selected if you choose gcc>=4.3.0, but you

can say 'Y' here if you want to build those two libraries for the other
|
|
components (that don't select them by default).

gcc-4.4.0 and above requires PPL and CLooG/PPL to build some parts
|
|
of the optimiser (GRAPHITE loop optimisation, to be precise).
|
|
|
|
In addition to those, gcc-4.4 also optionally uses MPC to enable
|
|
additional optimisations on complex numbers. Although MPC is optional,
|
|
crosstool-NG requires it and uses it to build gcc >= 4.4.0.
|
|
|
|
These will be automatically selected if you choose gcc>=4.4.0, but you
|
|
can say 'Y' here, although it is unknown yet if any other component
|

can use them.

It is highly recommended to check the newly built companion libraries.
|
|
Unfortunately, this is a very intensive task, and takes a loooong time.
|
|
|
|
Checking the newly built companion libraries is thus disabled by default,
|
|
but it is suggested that you check them at least once on your machine,
|
|
and if they work, disable the check on subsequent builds.
|
|
|
|
If you suspect that one (or more) of your companion libraries is the
|
|
cause for incorrectly generated code, you should answer 'Y' here.
|
|
Note however that this will take a really long time. For example,
|
|
building PPL on my machine takes roughly 1'40", while checking it takes
|
|
about 1h40'...

Also build companion libraries for the target. This can be usefull if
|
|
you want to later build a compiler that will run on the target, or if
|
|
you want to run gdb natively on the target.
|
|
|
|
Please note that for now, crosstool-NG can only build GMP and MPFR so.
