Move mmap in the runtime linker check to the RTS configure
`AC_DEFINE` should go there instead.

rts configure: Move over `eventfd`, `__thread`, and mem mgmt checks
All of this should boil down to `AC_DEFINE` not `AC_SUBST`, so it
belongs in the RTS configure and should be safe to move without
modification.

07717bf8 by John Ericson at 2023-09-22T15:34:54-04:00
Split `FP_CHECK_PTHREADS` and move part to RTS configure
`NEED_PTHREAD_LIB` is unused, and so no longer defined.
Progress towards #17191

Move visibility and clock/timer fun checks to RTS configure
Actual library check (which will set the Cabal flag) is left in the
top-level configure for now.
Progress towards #17191

ef058167 by John Ericson at 2023-09-22T15:35:15-04:00
Move leading underscore checks to RTS configure
`CabalLeadingUnderscore` is done via Hadrian already, so we can stop
`AC_SUBST`ing it completely.

Move alloca, fork, const, and big endian checks to RTS configure
All of this should boil down to `AC_DEFINE` not `AC_SUBST`, so it
belongs in the RTS configure and should be safe to move without
modification.

Adjust `FP_FIND_LIBFFI`
Just set vars, and `AC_SUBST` in top-level configure.
Don't define `HAVE_SYSTEM_LIBFFI` because nothing is using it.

cc5798a4 by John Ericson at 2023-09-22T15:35:15-04:00
Split BFD support to RTS configure
The flag is still in the top-level configure, but the other checks
(which define various macros --- important) are in the RTS configure.

Move function checks to RTS configure
Some of these functions are used in `base` too, but we can copy the
checks over to its configure if that's an issue.

Move/Copy remaining AC_DEFINE to RTS config
Only exception is the LLVM version macros, which are used for GHC
itself.

Get rid of all mention of `mk/confif.h`
The RTS configure script is now solely responsible for managing its
headers; the top level configure script does not help.
