Summarised this will be for multilib: * All libraries compiled for and used in 64-bit applications need to be installed in /lib64 or /usr/lib64. * All libraries compiled for and used in 32-bit applications need to be installed in /lib or /usr/lib. * All executables will still find its way in the regular /bin and /sbin paths. * The Operating System itself and all its libraries should only be compiled in 64 bit mode. It should not be a mix between 32 and 64 bit libraries. 32 bit support will only contain the libraries that are required by 32-bit-applications to link against. This is also conform what many distros derived from Redhat have in their setup. Note that Debian based distros follow a somewhat different setup. Note that we use the compiler toolchain to tell us at which paths we need to install the libraries. This means that if you build for a x86_64 target _without_ multilib support the libraries will likely end up in the classical /lib and /usr/lib directories, but that is completely steered by the compiler toolchain configuration. (it follows the location where the corresponding dynamic linker is expected to be installed) So, this change makes ptxdist follow the sysroot of the compiler toolchain more such that preliminary multilib support can be achieved. Preliminary in the sense that only still one C-library is being installed. In another changeset the support for a 2nd C-library installation will be added. At least after this change (and a few subsequent ptxdist makefile fixes) the /lib and /usr/lib area will only contain the contents that belong there in multilib environment.
