toolchain: move buildroot config files Handle the internal toolchain backend mechanism the same way we handle other backends. Signed-off-by: Yann E. MORIN <yann.morin.1998@anciens.enib.fr> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

# Config entries for internal toolchain backend
toolchain: use same gdb Config.in for internal/external toolchains We used to use different gdb configs for internal and external toolchains because mconf won't source the same file twice. This works, but is kind of sub optimal, as people forget to keep them in sync. Fix it to use the same file for both situations by shuffling around the config options a bit. Should work identical to before (except for the newer gdb versions available for ext).

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.

Rename BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed from "prefer static libraries when possible" to "use only static libraries". The former semantic didn't make much sense, since the user had absolutely no control/idea of which package would use static libraries, and which packages would not. Therefore, for quite some time, we have been starting to enforce that BR2_PREFER_STATIC_LIB should really build everything with static libraries. As a consequence, this patch renames BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS, and adjust the Config.in option accordingly. This also helps preparing the addition of other options to select shared, shared+static or just static. Note that we have verified that this commit can be reproduced by simply doing a global rename of BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

toolchain/buildroot: add comment for glibc NaN-2008 headers requirement Commit 4a5140ecf (toolchain/buildroot: glibc requires kernel headers >= 4.5 with NaN-2008) added a restriction on kernel headers for glibc when the architecture is using naN-2008. However, such a restriction is usually associated to a comment explaining the restriction, so the user knows what is happening. That comment was forgotten in 4a5140ecf. Add it now.

toolchain: musl support is no longer experimental Our musl support has now been around for quite some time, numerous packages have been fixed (although admittedly not all).

toolchain/toolchain-buildroot: PPC64(LE) support in musl requires ALTIVEC musl currently assumes all PPC64(LE) CPUs support ALTIVEC instructions. However, there are exceptions (such as the e5500) for which musl builds ultimately generate illegal instructions for the targets. Disable musl if the PPC64(LE) CPU does not support ALTIVEC instructions.

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. Reported-by: Vicente Olivert Riera <Vincent.Riera@imgtec.com> Signed-off-by: "Yann E.

glibc: add 2.19 as a supported version glibc 2.19 has been released recently (https://sourceware.org/ml/libc-alpha/2014-02/msg00224.html). This commit allows to build a toolchain with this new version. In order to allow this, we add a version selection that did not exist for glibc.

toolchain: use same gdb Config.in for internal/external toolchains We used to use different gdb configs for internal and external toolchains because mconf won't source the same file twice. This works, but is kind of sub optimal, as people forget to keep them in sync. Fix it to use the same file for both situations by shuffling around the config options a bit. Should work identical to before (except for the newer gdb versions available for ext).
