The gold linker cannot currently be built in a static toolchain build. This may get fixed in a future version of crosstool-NG. Also, there is a bit of weirdness here. versions of binutils >= 2.21 have GOLD (BINUTILS_HAS_GOLD), but that doesn't mean it should be used. For instance, if the architecture is not supported. So with that, we create a new hidden option: BINUTILS_GOLD_SUPPORT Which in turn depends on BINUTILS_GOLD_SUPPORTS_ARCH, BINUTILS_HAS_GOLD, and not STATIC_TOOLCHAIN... then replace anything that previously depended on BINUTILS_HAS_GOLD with our new BINUTILS_GOLD_SUPPORT option.

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