Description Michał Górny archtester

Right now, tc-getBUILD_* functions are completely disjoint from tc-get*. This may make sense for cross-compilation environments but the majority of Gentoo systems does not use it, and this simply means they force 'gcc' without any CHOST prefix, which in turn causes horrible distcc mismatches on my network.

I think that the functions should be modified so that:

a. if CBUILD is unset, it default to CHOST,

b. if CBUILD==CHOST, pure CC & co variables are respected.

Makes sense.

It doesn't look like your patch has been pushed yet. Anything holding it up?

Just forgot about it. Will merge it now-ish.

    toolchain-funcs.eclass: Use host vars in tc-getBUILD* when not cross
    
    Make tc-getBUILD* functions respect host variables (CC & co.) when
    not cross-compiling. This removes the necessity of overriding BUILD_*
    along with the regular variables on the systems that are not concerned
    about cross-compilation, and does not change the behavior for those
    which are.
