[Bug bootstrap/43301] New: top-level configure script ignores ---with-build-time-tools

./configure ... --with-build-time-tools=$MY_TOOLS ignores $MY_TOOLS (though it
correctly warns when $MY_TOOLS is not an absolute path).

Let's just say this led to extremely frustrating behavior until I decided to
start digging...

Suggested patch to correct the problem:

To be more specific, the gcc/as wrapper is generated with:

ORIGINAL_AS_FOR_TARGET=""
ORIGINAL_LD_FOR_TARGET=""
ORIGINAL_PLUGIN_LD_FOR_TARGET=""
ORIGINAL_NM_FOR_TARGET=""

Which causes the building of libgcc to fail later on at gcc/as line 83 with a
message about "exec: not found"

Actually I guess I can try taking it myself

JFTR, I had cause to use this today on powerpc-darwin9, and it seemed to DTRT -
so it would be useful to establish what it was that did not work before, that
was fixed by the patch.

/src-local/gcc-git-11/configure
--prefix=/opt/iains/powerpc-apple-darwin9/gcc-11-3Dr2d
--build=powerpc-apple-darwin9 --enable-languages=all --with-tune-cpu=G5
--enable-libphobos --with-libphobos-druntime-only CC=powerpc-apple-darwin-gcc
CXX=powerpc-apple-darwin-g++
--with-build-time-tools=/opt/iains/powerpc-apple-darwin9/gcc-11-3Dr2d/bin

Without the
"--with-build-time-tools=/opt/iains/powerpc-apple-darwin9/gcc-11-3Dr2d/bin" the
system linker and assembler are found and used (which fails to work with D,
causing a bootstrap fail) with the option, the relevant tools are found and
bootstrap succeeded....

(so I am not sure what the original problem was
since $build is not specified in the summary, I guess we must assume it was
i686-pc-cygwin so perhaps the problem is specific to that setup?)

Alexandre Oliva's assessment is that the issue was just one having an old build
left over, and that all the patch did was to force a rebuild:
https://gcc.gnu.org/pipermail/gcc-patches/2022-August/599169.html
(so we might be going with his patch instead)

So, current patch status is that we've got an idea that I just need to test,
along with possibly extending it to similar cases:
