…ARY_PATH` (#157) * [Runner] Fix CSL paths * [Runner] Move `csl_paths(host_platform)` at the beginning of `LD_LIBRARY_PATH` This should make it easier to run applications we build with our toolchain. * [Rootfs] Update to fix CSL libraries * [Runner] Override `LD_LIBRARY_PATH` inside the compiler wrappers * [Runner] Generate CSL paths only for target and host platforms Having all Intel Linux platforms in the CSL paths was a mess hard to deal with. The simplest thing to do is to generate the paths only for target and host, and sort them correctly: if they have same architecture, have the host first, if the have different architectures, have the target first. * Simplify reading of some buffers in tests * [Runner] Add helper function to set `LD_LIBRARY_PATH` * [Runner] Have always `host` first in CSL paths for `LD_LIBRARY_PATH` Having `target` first would make C++ programs for `i686-linux-musl` work, but then we can't run C++ programs for the host. We really need to fix the musl loader.
