will-it-run script to check linkage requirements and x86 extensions #1

theopolis commented 5 years ago

After a binary or library is built we want to check the linkage requirements.

  1. run ldd -v and check the glibc version requirement.
  2. check a small-list of expected dynamic link requirements (m, rt, pthreads, z)
  3. disassemble and search for vector/etc instructions that only exist on newer CPUs (non-deterministic check)
