headline: GCC now searches for machine-prefixed tools in additional locations.
tldr: GCC's `find_a_program` function now includes machine-prefixed program names (e.g., `x86_64-linux-gnu-as`) in its search paths for cross-compilation.

The find_a_program utility in GCC now intelligently searches for machine-prefixed programs, such as x86_64-linux-gnu-as, alongside existing search patterns. This enhancement addresses a long-standing issue in cross-compilation environments where GCC’s previous search logic often led to confusion by prioritizing unprefixed tools or platform-specific directory structures. By aligning with common cross-compilation practices and similar behaviors in other toolchains like Clang/LLVM, GCC makes tool discovery more intuitive and reliable for developers working with multiple architectures.
