I've split the patch in 5 parts:
- config: add option to build statically linked toolchain
- complibs: do not prompt for shared libs if static selected
- debug/gdb: global static forces static cross-gdb
- binutils/binutils: build statically
- cc/gcc: build final gcc statically

That way, if a component breaks but not the others (eg binutils breaks, but
gcc still works), it is easy to revert only the binutils part, not touching
the functional ones.

As for gdb, I took the other approach: your patch was hidding the "static"
option for the cross-gdb when global static was set. I choose to force it
(with a 'select'). That is IMHO better, for two reasons:
- first, the user sees the same option set in the menu,
- second, it makes the code one line smaller :-)

I applied the same for the static libstdc++ in gcc: force it rather than
hide it.

I will reply with my series later, after I've done a few tests...
