This commit adds a target package "gcc-final", which is a target package responsible for installing the gcc runtime libraries to STAGING_DIR and TARGET_DIR. This task was so far done by the host gcc-final package. The motivation for splitting it up into a target package is to be able to properly handle the licensing situation of GCC, where the host part of GCC (the compiler itself) is under GPLv3, but the runtime libraries on the target are under GPLv3-with-exception. So far, we were not handling at all the license of gcc. So what this commit does is: * Add a gcc-final target package, which is depended on by the toolchain-buildroot package, and which depends on host-gcc-final. * Moves to gcc-final the logic for installing target/staging libraries Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Romain Naour <romain.naour@smile.fr>

|
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.
