OpenBSD doesn't have this library and so the linker complains:
ld.lld: error: unable to find library -ldl

Previously it was unclear whether req_shared_libs should require:

 * that the platform supports dynamic library loading,
 * that GHC supports dynamic linking of Haskell code, or
 * that the dyn way libraries were built

Clarify by splitting the predicate into two:

 * `req_dynamic_lib_support` demands that the platform support dynamic
   linking
 * `req_dynamic_hs` demands that the GHC support dynamic linking of
   Haskell code on the target platform

Naturally `req_dynamic_hs` cannot be true unless
`req_dynamic_lib_support` is also true.

It fails on statically-built Alpine with
```
T13702.hs:1:1: error:
    Could not find module ‘Prelude’
    Perhaps you haven't installed the "dyn" libraries for package ‘base-4.15.0.0’?
    Use -v (or `:set -v` in ghci) to see a list of the files searched for.

Reverts many of the testsuite changes

By default we don't link the RTS when linking shared libraries because in the
most usual mode a shared library is an intermediary product, for example a
Haskell library, that will be linked into some executable in the end. So we
wish to defer the RTS flavour to link to the final link.

However sometimes the final product is the shared library, for example when
writing a plugin for some other system, so we do wish the shared library to
link the RTS.

For consistency we also make -staticlib honor this flag and its inversion.
-staticlib currently implies -flink-shared.

glibc 2.30 disallowed dlopening PIE objects, so just remove the test.
Fixes #17952.

Fixes test T3807 when building with Hadrian.

Trac #16370

This eliminates most uses of run_command in the testsuite in favor of the more
structured makefile_test.

This reverts commit 76c8fd67.

Previously due to #12759 we disabled PIE support entirely. However, this
breaks the user's ability to produce PIEs. Add an explicit flag, -fPIE,
allowing the user to build PIEs.

Before ghc-7.2 hs_add_root() had to be used to initialize haskell
modules when haskell was called from FFI.

commit a52ff761
("Change the way module initialisation is done (#3252, #4417)")
removed needs for hs_add_root() and made function a no-op.
For backward compatibility '__stginit_<module>' symbol was
not removed.

This change removes no-op hs_add_root() function and unused
'__stginit_<module>' symbol from each haskell module.

The name 'os' clashes with a python library

We now pass the "always" flags to Makefile tests as well as python tests.

The test previously used +RTS -? as an example flag that is banned in
the -rtsopts=some mode. That flag is now allowed, so we pick -c instead.

We were getting the RTS linked twice, which caused odd things to happen.
