27 | # This becomes the value of INSTALLTOP in Makefile | |

34 | # | |
35 | # --cross-compile-prefix Add specified prefix to binutils components. | |

37 | # --api One of 0.9.8, 1.0.0 or 1.1.0. Do not compile support for | |

45 | # [no-]threads [don't] try to create a library that is suitable for | |
46 | # multithreaded applications (default is "threads" if we | |

49 | # no-asm do not use assembler | |
50 | # no-dso do not compile in any native shared-library methods. This | |

52 | # no-egd do not compile support for the entropy-gathering daemon APIs | |
53 | # [no-]zlib [don't] compile support for zlib compression. | |
54 | # zlib-dynamic Like "zlib", but the zlib library is expected to be a shared | |
