20 Linaro is maintaining some advanced/more stable/experimental versions
21 of gcc, especially for the ARM architecture.
23 Those versions have not been blessed by the gcc comunity (nor have they
24 been cursed either!), but they look to be pretty much stable, and even
25 more stable than the upstream versions. YMMV...
27 If you do not know what this Linaro stuff is, then simply say 'n' here,
28 and rest in peace. OTOH, if you know what you are doing, you will be
29 able to use and enjoy :-) the Linaro versions by saying 'y' here.
