Build relocatable versions of tools
debian: Install tools with canonicalized multiarch prefix
Create a symlink with $(DEB_HOST_GNU_TYPE) in the name for compatibility with AC_CHECK_TOOL.
(For example this produces a file
/usr/bin/i686-linux-gnu-capsule-capture-libs and a symlink
/usr/bin/i686-linux-gnu-capsule-capture-libs -> i386-linux-gnu-capsule-capture-libs on recent Debian/Ubuntu i386)
debian: Build relocatable versions of libcapsule binary tools
When built on a system with the oldest glibc version that is to be supported, these tools are suitable for bundling in projects that need to run on an arbitrary host system and make use of libcapsule when preparing a container.
(It's easier to make these part of a package, for example built for SteamRT 'scout' or 'heavy', than to build them separately.)
