I'd say that we shouldn't limit the concept of 'toolchain' to specifically GNU binutils + GNU gcc. Configure scripts can require much more tools (like assemblers, *-config tools including pkg-config) and I doubt we should really assume they all have some magic support for ABI switching we had taken care of. That said, it would be actually more reasonable to have three separate triples for those ABIs, and link them to the same application if it supports all three ABIs. Of course, we would need to ensure that the application actually respects the triple via which it was called. I think that would be cleaner than explicitly overriding compiler options, and things such as PKG_CONFIG_PATH. But I guess many people will disagree. --=20 Best regards, Micha=C5=82 G=C3=B3rny --Sig_/7DZmiq9++6KvjMJ6rLvVeH1 Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQJ8BAEBCgBmBQJSwJxyXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2REJCMDdDQzRGMERBRDA2RUEwQUZFNDFC MDdBMUFFQUVGQjQ0NjRFAAoJELB6GurvtEZO8+YQAL8AEl9BTGGCMpKpEve+FIEZ b0HXAp+4S0ovd1sVqCsS8arg50qrjrVgQDe1fS65ghSXV/BhUCTPFhEbgEOHQZfT 0slZVBm9WNh9Hke79d28GpRFqG2RUZAvLN2KpYH6mnzBrpJlKMV/at5GaMQCHFE0 9kttuID6HTtg5WR3taGhZd8uH2J6vAZyRGNkiXj/RP4BU6SXDznBJUD88YTvFWOX TTxAnB+koADlKuA3lyO3V8Td8ICSOedj6XCjK0kqFSFhqR9fQJNqKm5BuCxKEU3C lyiuTf5vvjfKDHYMj5feDtyhgV8ZagG1upROYJkhXuYRN9kebvZny4ImPTW7T2Wm fDp8vYAQ29IsGn8xP/QDBbN/TRukeij4oYaPmCMwuCLP4DA5NkuZSu39R7VkV5kr kGZClFrgX6ONa/0U3iKbYtl2Jk1sRnbff4HR3u6JL2Z3uOotU9DQYigIiLfYVJu7 DWdLKVgLHRVL0NCb7PdS6L+CNndDsEEU0l/0q199jvnd0mNDDlLOCgk30K7Zd6SZ tvKkrZJcJ9+1Z9u4K1feGqsQ6YfngrVtoU84Y6sHIFft23oweOt537OgwR249QFV cUl9Wvo8yTMAE8nRawWnq0pT/AHjv4Gre9LtZyZEbW/gj0XbFOup/d0HfNw2lc/x ySGd8ILWxEnaFP7gx2jo =FSFG -----END PGP SIGNATURE----- --Sig_/7DZmiq9++6KvjMJ6rLvVeH1--
