test/Makefile and tests/choosetests: disable libdl tests entirely due to TLS storage issue:
  <Shiz> ERROR: Attempt to change TLS address.
  <Shiz> from my understanding, that happens when the julia-global TLS state is being set twice 
  <Shiz> but I'm not sure what causes it -- we don't use the ifunc functionality as we don't use glibc,
         and the only reference to the TLS setter function I can see is in ui/repl.c
  <Shiz> I guess the issue is that ui/repl.c somehow gets included into the .so that libdl attempts to load
test/spawn.jl: ENFILE is just as valid to return as EMFILE when the system runs out of fds;
test/cmdlineargs.jl: the backtrace symbols are broken on multiple platforms, including musl;
test/file.jl: fakeroot makes the stricter permission checks fail;
test/read.jl: ditto.
