In this commit BR2_PACKAGE_MUSL_SUPPORTS looks redundant with BR2_PACKAGE_MUSL_ARCH_SUPPORTS, but for other C libraries, like glibc, it can be different. To be consistent, we use the same pattern for musl. Signed-off-by: James Hilliard <james.hilliard1@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Yann E.

|
|
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.
