- help
- This option allows to customize the "vendor" part of the
- toolchain tuple, where the toolchain tuple has the form
- <arch>-<vendor>-<os>-<libc>. The default value, "buildroot",
- is fine for most cases, except in very specific situations
- where gcc might make different decisions based on the vendor
- part of the tuple. The value "unknown" is not allowed, as the
- cross-compiling toolchain might then be confused with the
- native toolchain when the target and host architecture are
- identical. The value can not be empty either.
- If you're not sure, just leave the default "buildroot" value.
