Move via-C flags into GHC

These were previously hardcoded in configure (with no option for
overriding them) and simply passed onto ghc through the settings file.

Since configure already guarantees gcc supports those flags, we simply
move them into GHC.

ghc-toolchain: Rename readProcess to readProcessStdout

Fixes bugs regarding a translation from the original autconf program
that failed to account for the exit code.

The longer name reenforces that we really only care about the stdout,
and the exit code and stderr of the program are irrelevant for the case.

Delete CMD_OPTS_STAGEX

Instead of having configure configure different options for different
programs depend on the stage, we delete this completely and have hadrian
select the correct target toolchain configuration file depending on the
stage, from which it can read those options.

Revert "Rip more of configure that is no longer being used"

I realized we still need this function in rts/configure.ac

This reverts commit 01f5d4b480f4ab1514ac0a4fc957db199d1a0279.

Revert get_arm_isa deletion from 74f03f243d08aa910d39cdd9dadb976e9386283a

As in the previous commit, we still need this info from the rts
configure script.

I suppose it could be useful for the rts to also read somehow the
toolchain information...
