hadrian: `need` any `configure` script we will call

Make it easier to debug Cabal configure
Right now, output is squashed. This make per-package configure scripts
extremely hard to maintain, because we get vague "library is missing"
errors when the actually probably is usually completely unrelated except
for also involving the C/C++ toolchain.
(I can always pass `-VVV` to Hadrian locally, but these errors are
subtle and I often cannot reproduce them locally!)

rts: Move most external symbols logic to the configure script
This is much more terse because we are programmatically handling the
leading underscore.
`findPtr` however is still handled in the Cabal file because we need a
newer Cabal to pass flags to the configure script automatically.

Move lib{numa,dw} defines to RTS configure
Clean up the m4 to handle the auto case always and be more consistent.
Also simplify the CPP --- we should always have both headers if we are
using libnuma.
"side effects" (AC_DEFINE, and AC_SUBST) are removed from the macros to
better separate searching from actions taken based on search results.
This might seem overkill now, but will make shuffling logic between
configure scripts easier later.
