Hi !

I use those links when some compilations are broken (maybe configured for toolchains ?)

ln -s /usr/bin/gcc /usr/bin/arm-none-linux-gnueabi-gcc
ln -s /usr/bin/g++ /usr/bin/arm-none-linux-gnueabi-g++
ln -s /usr/bin/c++ /usr/bin/arm-none-linux-gnueabi-c++
ln -s /usr/bin/as /usr/bin/arm-none-linux-gnueabi-as
ln -s /usr/bin/ar /usr/bin/arm-none-linux-gnueabi-ar
ln -s /usr/bin/nm /usr/bin/arm-none-linux-gnueabi-nm
ln -s /usr/bin/ranlib /usr/bin/arm-none-linux-gnueabi-ranlib
ln -s /usr/bin/strip /usr/bin/arm-none-linux-gnueabi-strip
ln -s /usr/bin/pkg-config /usr/bin/arm-none-linux-gnueabi-pkg-config

Do you see more to add ?

alternatives is used for this mostly

but i use a old school shell script to change the compiler

that ,above, looks about right

but for some of those you might want to use a "config.site" and export option to set things like pkg-config and locations of lib's and includes
