toolchain: include C libraries in legal-info So far, the legal-info infrastructure was not exporting the legal info for the C libraries. This is because the legal-info only acts on packages defined in $(TARGETS). But the C libraries are never added to $(TARGETS), since there is no corresponding BR2_PACKAGE_<C-LIBRARY>. This patch adds such symbols for the 4 C libraries we support in our internal backend: uClibc, glibc, eglibc and musl. Signed-off-by: "Yann E.

package/m*/Config.in: fix ordering of statements The check-package script when ran gives warnings on ordering issues on all of these Config files. This patch cleans up all warnings related to the ordering in the Config files for packages starting with the letter m in the package directory. The appropriate ordering is: type, default, depends on, select, help See http://nightly.buildroot.org/#_config_files for more information.

package/c-libraries: need linux-headers Now that we check that a target package in the _DEPENDENCIES of another package has to be enabled in config, all target packages must have a kconfig symbol. Add a Kconfig symbol for linux-headers, and select it from the packages that depends on it (C libraries). Also remove the now-misleading comments "for legal-info" from the C libraries.

musl: no SSP on i386 and PowerPC Due to what appears a bug in gcc according to the musl developers, but that the gcc developers don't want to fix, SSP support currently don't work on i386 and PowerPC with musl. Additional details can be found at: http://www.openwall.com/lists/musl/2016/12/04/2 OpenWRT and Alpine Linux both have musl and gcc patches to work around the issue, but in the context of Buildroot, we at this point don't care enough about SSP support specifically with musl on those architectures to carry additional patches. Currently, having SSP enabled with musl/i386 causes a number of build failures in the autobuilders: cups, ipmiutil, openssh, ruby, stunnel, sudo and mosh at least all fail to build because of this. So we simply disable SSP support in the toolchain when musl is used on i386 and PowerPC. The PowerPC case is not tested in the autobuilders, but has been reproduced locally and is also fixed by this patch. Fixes: mosh http://autobuild.buildroot.net/results/60aa12f1aed08e3b7a98f9ce7091bee3a44d692c/ ipmi-util http://autobuild.buildroot.net/results/fb9a071b8739527f424cfe2886ec480f438f70ab/ cups http://autobuild.buildroot.net/results/486dea944d6ecba5c4e6e8ac664261c1909f4b4c/ openssh http://autobuild.buildroot.net/results/742a8bf4726de6e9ba6926e3fb6019a434454e48/ sudo http://autobuild.buildroot.net/results/682531f368c4e982cafe9e625dd41f6d8c7f93f9/ ruby http://autobuild.buildroot.net/results/dac660f96c7f85e933a6b82cf61edd429eeae9aa/ stunnel http://autobuild.buildroot.net/results/cee52505f1ac2da2f5ba86c9ebfd1f5cd9e301be/ Thanks to Yann E.

package/musl-compat-headers: provide compatibility headers not in musl musl provides neither sys/queue.h nor sys/cdefs.h. Those two headers are however quite widely used in a lot of packages (though they should at least not use cdefs.h which is only full of mostly-legacy macros, and which is mostly an internal header of glibc and was never really meant to be exposed to, and used by packages). But we don't live in an ideal world, so a lot of packages break when those two headers are missing. We already took care of sys/queue.h with the netbsd-queue package. But the need for cdefs.h is getting more and more pressing. We rename the netbsd-queue package into musl-compat-headers, and we make it install sys/queue.h (from NetBSD) and sys/cdefs.h (a minimalist one we bundle in Buildroot). We can't use the cdefs.h from NetBSD because it includes machine-dependent headers; instead we bundle a very minimalistic one, that covers only what we need. Signed-off-by: "Yann E.
