8296904: Improve handling of macos xcode toolchain

[RealCLanger]

This is a backport of JDK-8296904. Changes to make/autoconf/basic.m4 from jdk17u-dev apply cleanly.
I resolved building.md to the state of jdk11u-dev and regenerated the html files with Pandoc 2.3.1. This also modified testing.html.

looks like we test in basic.m4 for DEVKIT_ROOT in the if check, but we do not use it afterwards and go directly to UTIL_LOOKUP_PROGS using TOOLCHAIN_PATH.
This seems to be different in head
https://github.com/openjdk/jdk/blob/470f3424fcce0e41b75cccdd5e3a56771cd07ff5/make/autoconf/basic.m4#L137

but on the other hand we do it in 17u-dev the same way. So probably the backport is okay, but maybe not optimal (comparing to head) ?

[RealCLanger]

Hi, as I've already commented in the 17u-dev PR, this would be fixed with backporting JDK-8287254, something we could/should consider independently.
