use RUNPATH again, and prepend LD_LIBRARY_PATH correctly, but...

doesn't solve the problem of being able to specify libs, like we wanted
to do on Pal, because whatever's in LD_LIBRARY_PATH will still be
prepended by srun_prolog
remove old glob in bin/CMakeLists.txt
fix misformatted table
fix symlinking
prepend LD_LIBRARY_PATH unless Igor says it's overriding it
Merge branch 'master' into runpath-ld-lib-path
use new Igor command: 'require_relative_to_symlink' in igor_new_bfs.rb
append to LD_LIBRARY_PATH so we can find libstdc++
add path to MPI libs to RUNPATH
fix signal handling on segfault (use google stacktrace)
update igor scripts to use 'require_relative_to_symlink'
Merge branch 'runpath-ld-lib-path' into compiler
make sure not to freeze on error
igor_common: fix sbcast
