# Config entries for internal toolchain backend
if BR2_TOOLCHAIN_BUILDROOT
config BR2_TOOLCHAIN_BUILDROOT_VENDOR
string "custom toolchain vendor name"
default "buildroot"
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.
