OK, making progress here. Finally I got gcc rebuilt but I had to modify the |
| 24 |
toolchain.eclass |

The gmp, mprf and mpc lib locations were needed to even configure gcc. The |
| 42 |
dynamic linking was needed so that building >=stage1 used the prefix-provided |
| 43 |
linker and not the host-provided one. Most things build but my fortran compiler |
| 44 |
is broken. |

The include path is odd but I don't think that's the stopper. Both gcc and |
| 58 |
glibc were rebuilt and were the ones use before the switch to the standalone |
| 59 |
profile. The secure_getenv did appear as a QA when installing gcc |
