Rework CC/CC_STAGE0 handling in `configure.ac`
Rather than using the non-standard/idiomatic `--with-{gcc,clang}=...`
scheme use the `CC=...` style scheme.
The basic idea is to have Autoconf's CC/CFLAG/CPPFLAG apply to
stage{1,2,3}, while having a separate _STAGE0 set of env-vars
denote the bootstrap-toolchain flags/programs.
This should be simpler, less confusing, and somewhat more in line with
Autoconf's idioms (allowing us to reuse more of Autoconf rather than
(re)inventing our own confusing non-standard m4 macros to do stuff that
Autoconf could almost do already for us)
Morever, expose CC_STAGE0 as a so-called "precious" variable.
So now we can better control which bootstrapping gcc is used
(by default the one used by the stage0 ghc, unless CC_STAGE0 is
overriden)
```
Some influential environment variables:
CC_STAGE0 C compiler command (bootstrap)
CC C compiler command
CFLAGS C compiler flags
...
Use these variables to override the choices made by `configure' or to
help it to find libraries and programs with nonstandard names/locations.
```
Test Plan: I've tested that cross-compiling with
`--target=powerpc-linux-gnu` still works, and tried a few variants of
settting `CC=` and `CC_STAGE0=`; `./validate` passed as well
