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.

sh4: fix toolchain creation
The Linux kernel does force compile with -m4-nofpu, which is only
available when building a multilib toolchain.
The interesting part here is, that buildroot use --disable-multilib for
gcc configure, but enables --with-multilib-list=m4,m4-nofpu in
the default configuration for Qemu targeting r2d emulation.
This results in a toolchain, which can be used for the kernel and
for userland without creating a multilib toolchain with different
kinds of libgcc version. In the multilib case there would be
subdirectories created (!m4 and m4-nofpu). As buildroot uses a
short version of toolchain creation, a multilib enabled gcc build
fails when creating libgcc.
So the best solution is to just keep multilib disabled, but always
add --with-multilib-list when sh4/sh4eb/sh4a/sh4aeb is choosen.
Tested with sh4/sh4a toolchain build and qemu defconfig with
gcc 4.8.x/4.9.x (with and without C++ enabled), uClibc and glibc.
Disable sh4a/sh4aeb for uClibc, as it does not implemented, yet.

toolchain: also source the musl package
We do source the glibc and uClibc packages in the toolchain menu,
because they do provide user-visible options. However, we do not so
far source the musl Config.in file
However, in 822be87 (toolchain: include C libraries in legal-info),
a Config.in file for musl was explicitly created, so that:
- legal-info would work (needed at the time, probably no longer needed
nowadays),
- the appropriate packages are enabled, like netbsd-queue or kernel
headers.
Yet, we do not source musl/Config.in, which means we do not get
netbsd-queue or kernel-headers to be selected:
$ make distclean; make menuconfig
Toolchain --->
C library ---> musl
save-and-exit
$ grep BR2_PACKAGE_LINUX_HEADERS .config
[nothing]
$ grep BR2_PACKAGE_NETBSD_QUEUE .config
[nothing]
Fix that by sourcing musl/Config.in at the same place we source glibc
and uClibc.
Normally, we do have a check in place that verifies that a package
that is not enabled is not a dependency of another package that is
enabled. However, musl is only a dependency of host-gcc-final, which
is a host package and has no corresponding BR2_PACKAGE_HOST_GCC_FINAL.
Thus host-gcc-final is not in the PACKAGES variable, and thus does not
trigger our check.
