Very rarely on old GCCs, we'll complaints about GCC itself being handed

Enabling this functionality with GCC is pointless -- we don't roll it,

-grecord-gcc-switches causes the compiler and compiler flags to be
stored in the produced debug information. This causes Goma builds to
be non-deterministic, because the compiler path differs depending
on whether the compiler was run locally or on Goma. This, in turn,
causes cache pollution and needless work. Since we are not in
fact using the information stored by -grecord-gcc-switches, this
change disables it. We can re-enable it when we want to start
using the information, provided we come up with another way to
avoid the issues described earlier.

This CL is a wild guess that tries to work around what appears to be an
incredibly rare Go runtime bug
(https://github.com/golang/go/issues/24484). As mentioned on the
chromium bug, apparently execve is taking a while... somehow, and
`pthread_create` fails with `EAGAIN` concurrently.
So the intent here is to `fork()` + `exec()`. `fork()` will
a) dispose of the thread that's trying to `pthread_create`
b) isolate the `exec` in its own process, so the parent's runtime can
spin up as many threads as it likes in peace.
This slows down an 'ideal' kernel build (aka a build where ccache is a
100% hit rate, so the compiler wrapper's overheads are very pronounced)
by ~4% in my measurements.

Write the warning report to stdout (surrounded by a tag
<LLVM_NEXT_ERROR_REPORT>). Currently OUT_DIR only gets passed to local
compiles, and so remote compiles can't do the double build. Even if
they write to /tmp, RBE or Goma won't know to copy them as part of the
output.
Packaging the warnings reports is a problem as well since the additional
build step needs extra surgery in soong (it's not possible to add a
dangling, optional build step in Ninja).
Writing the reports to stdout conveniently solves both these issues. We
can just scrape the reports with a script.

-warnings-as-errors). The error message will also have
"warnings-as-errors". So,
1. Trigger double-build if "warnings-as-errors" is in *stdout*.
Clang-tidy will also fail if clang issues a Werror diagnostic. In this
case, we'd get "clang-diagnostic" in stdout. Do a re-build in both
these cases.
2. Remove flags containing "-warnings-as-errors" in the rerun. Unlike
-Werror/Wno-error, clang-tidy doesn't have a -no-warnings-as-errors to
override a prior -warnings-as-errors. Existing double-build processing
will disable -Werror flags to Clang.

If this option is specified, we'll build a fully static binary, rather
than having it link with libc. If unspecified, our behavior shouldn't
differ from what we have today.

This reverts commit 3b2358092e00ab7904a873b516ac6aac832c2277.
According to crrev.com/c/2171058, the fix in chromium could work.
Will wait till the patch submitted in chromium and CrOS uprevs to
merge the change into CrOS.
Reason for revert: The workaround is not needed anymore.

Linux does a lot of "is this flag supported" testing by passing
/dev/null as an input file. Since this code is pretty heuristic-y
anyway, let's see if we can get by with calling that a `configure`-like
file. :)

Fresh chroots might not have all of these GCCs emerged. Just `continue`
if that's not the case.
This also fixes failing lints.

There are some ebuilds that (unfortunately) run configure steps inside
of their regular `make` invocations. Rather than trying to fix those as
they pop up, add a heuristic to our -Wno-error bits. This is similar to
a heuristic goma added a while back when experimenting with full builds
of CrOS using goma.

Rather than turning all of stderr into a string here, we can turn the
thing we're searching for into a []byte. Should shave off a few cycles,
and is just as readable.

Not `return`ing here was troublesome for our monitoring infra, since it
meant that _any_ clang error that mentioned '-Werror', with this support
turned on, would turn into a json file. With configure steps and the
like, this probably isn't the behavior that we want.

CCACHE_BASEDIR used to be set to sysroot so that ccache can reuse
compilation results across different boards. This is not useful
on builders and also less useful for board builds since we set
closer to target CFLAGS now.
It also breaks use of -fmacro-prefix-map option in clang/gcc.
So rip it out and simplify the rest of code.
