suggestion for toolchain to have its own directories

[Sid]

How about going with a toolchain directory for the base system only. It would use shared files, and have subdirectories specific to clang, gcc, or other compiling components or versions. This way it is both modular and organized.

For instance: /usr/toolchain/bin/, /usr/toolchain/sbin/, and /usr/toolchain/lib/ can be used for shared files. /usr/toolchain/clang/, /usr/toolchain/gcc/, etc, and their (lib, sbin, bin, include) subdirectories can be used for specifically needed files. The old directories can be softlinked to there.

Any drastic changes can only be tried in the head branch. Port compilers should definitely be left alone, by not using /usr/local/toolchain/* at all.

Things that actually are private to a compiler are in separate directories (see /usr/lib/clang, for example).
