    atf: Fix ATF_BUILD_* values when not using the bootstrap compiler
    
    Currently, we encode the full path and compile flags for the build
    compiler in libatf. However, these values are not correct when
    cross-compiling: For example, when I build on macOS, CC is set to the
    host path /usr/local/Cellar/llvm/11.0.0_1/bin/clang-11. This path will
    not exist on the target system.
    Simplify this logic and use cc/cpp/c++ since those binaries will exist
    on the target system unless the compiler was explicitly disabled.
    I'm not convinced ATF needs to encode these values, but this is a
    minimal fix for these tests when using a non-bootstrapped compiler.
