Thank you for the explanation and research! |

Tangental to this, mgorny wrote a little tool yesterday that might |
28 |
work well as an alternative to crossdev for multilib systems. It |
29 |
simply wraps all the native toolchain calls with proper -m and |
30 |
provides the new CTARGETs. |

If anybody wants to take a look, this is the link he posted on -dev : |

Whether or not this suits everyone's needs for an i686 crossdev on |
37 |
amd64 systems, i don't know. Thoughts? |
