The previous method used to determine the --gcc-install-dir relied on
'ls' over the gcc installation path, which was fragile and failed in
cases where the external toolchain contained multiple gcc versions or
paths [1].
We replace it a more reliable approach using:
$(TARGET_CC) -print-search-dirs
This helps setup to register the desired GCC architecture if a
given toolchain packages includes multiple GCC architecture
installations. Which isn't possible using the actual method using 'ls'.
For example from James's report:
└── /opt/container/my-toolchain-2025.01.01.12345/lib/gcc/
├── aarch64-example-linux-gnu/
│ └── ...
├── i686-example-linux-gnu/
│ └── ...
└── x86_64-example-linux-gnu/
└── ...
Thanks to Romain Naour for suggesting this improved method.
