collect2: error: ld returned 1 exit status

Reproduce the command from src using ggml-bitnet-mad.cpp and ggml-bitnet-lut.cpp with the listed include paths, then inspect the linker errors for the missing main, ggml_row_size, and fmax symbols. Compare this with the repository's supported build entry point; the issue is done when the documented aarch64 compilation path completes successfully.
