Raw Normal View History

Add the full crosstool-NG sources to the new repository of its own. You might just say: 'Yeah! crosstool-NG's got its own repo!". Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup. That means I'm putting backups in place in the afternoon. That also means we've lost history... :-(

uClibc: Fall back to default configs if not provided I've added the .config files to contrib/uClibc-defconfigs from buildroot to use as default configs if they are not provided in the sample. If a particular architecture really needs an option set, it should be either updated in the manange_uClibc_config function in scripts/build/libc/uClibc.sh or a custom ${uclibc_name}.config should be added to the sample (usually via `ct-ng saveconfig`).
