8300805: Update autoconf build-aux files with latest from 2022-09-17

[gnu-andrew]

I came across this patch when trying to work out how to backport JDK-8285630 to fix the RISC-V Zero build. That fix is only available in 17u as part of a huge patch to bring in the RISC-V JIT port. It turns out that this autoconf update supersedes both that change and JDK-8265192, an additional MacOS on AArch64 fix, by updating the over a decade old autoconf files to new versions which natively support architectures like AArch64, RISC-V and LoongArch which the JDK has had to add overrides for.

The backport is not clean because of those two earlier fixes being absent in 11u and the lack of Windows WSL support added by JDK-8215445 and JDK-8257679

FWIW, this builds fine in rhel-8.10 / gcc 8.5.0 / autoconf 2.69.

I have tested risc-v cross-build of this PR (x86_64 debian trixie build OS + risc-v debian trixie sysroot + temurin boot jdk). Configured with:
bash configure --with-jvm-variants=zero --openjdk-target=riscv64-linux-gnu --with-sysroot=$SYSROOT --with-boot-jdk=$BOOT_JDK --with-zlib=bundled --enable-debug

Build finished successfully. Resulting binary works on risc-v board (also debian trixie, done just --version test).
