</div></div></blockquote><div>You _may_ require different toolchains for different processor with same arch types, for example under x86, i386 and i586 toolchains _may_ be used interchangably but not ia64 or x86_64 or may not even for atom. Similarly in ARM, there are different families of processor and there may be big endian or small endian processor. So you may have to find the correct toolchain for the given config.<br>

I am not sure if you understand this or not, but you need to have a series of toolchains for each arch you need to cross compile at different locations.<br>For different binaries of different arch, I would suggest you use different directories of same source code. Generally make clean or distclean should get rid of most binaries, but starting a clean build is always the best idea. <br>
Toolchains can be bit of a pain to get right. <br></div><blockquote style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="font-size:10pt;font-family:Courier New,courier,monaco,monospace,sans-serif">

pretty much on most distribution, you can install ncurses and go for make menuconfig and then just make(i.e. if you are native compiling the kernel). <br>However the config for distributions are fairly complex these days, so you may require to build few other things like initrd and create devices files and all.
