I suggest using a bin directory in a multiarchified /usr/lib path, like e.g. wine and qt4 are doing. Example files are: /usr/lib/x86_64-linux-gnu/qt4/bin/qmake (package is qt4-qmake:amd64) /usr/lib/x86_64-linux-gnu/wine/bin/wine (package is wine64:amd64) In addition you can put a wrapper script in /usr/bin, which calls the binary in /usr/lib accordingly. Maybe something like 1. extract target file from parameters 2. determine target file's architecture from ELF headers 3. translate ELF architecture into gnu triplet 4. call matching binary in /usr/lib/ -- Sebastian
