sys-devel/gcc-12.1.0: workaround compilation issue on arm64-darwin |
| 9 |
|
| 10 |
For some reason when flex invokes m4 during bootstrap of gcc, it fails |
| 11 |
which results in an empty file, causing compilation to fail. This is a |
| 12 |
really weird issue only happening on arm64/Apple SI, so just use the |
| 13 |
host flex which seems to work correctly. |
