* build: Allow kernel modules to set build ID debug symbolFelix Fietkau2015-10-301-1/+2
| | | | | | | | | | | | | | | | | | | | This change adds support for specifying a build ID for kernel modules. This is done by setting PKG_BUILD_ID to a hexadecimal string, which will then be passed to the kernel linker. In addition, when this flag is set, the build ID debug symbol (.note.gnu.build-id) will not be stripped from the kernel module. This symbol is exported in sysfs by the kernel (if the kernel is compiled with CONFIG_KALLSYMS) and so can be used to uniquely identify a version of a kernel module in a running kernel. This is useful for keeping track of different versions of a module when doing experiments and development. Modules that specify the build ID will be ~100 bytes larger (depending on the length of the build ID specified). There is no size difference for kernel modules that do not set this variable.

* build: use gcc-provided ar, nm and ranlib where appropriateFelix Fietkau2014-12-271-5/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since GCC 4.7, GCC provides its own wrappers around ar, nm and ranlib, which should be used for builds with link-time optimization. Since GCC 4.9, using them actually necessary for LTO builds using convenience libraries to succeed. There are some packages which try to automatically detect if gcc-{ar,nm,ranlib} exist (one example is my package "fastd" in the package repository, which tries to use LTO). This breaks because the OpenWrt build system explicitly sets the binutils versions of these tools. As it doesn't cause any issues to use gcc-{ar,nm,ranlib} instead of {ar,nm,ranlib} even without LTO, this patch just makes OpenWrt use the GCC-provided versions by default, which fixes the build of such packages with GCC 4.9. (I know that builds fail though when clang is used with -flto and gcc-{ar,nm,ranlib}, but as all OpenWrt toolchains are based on GCC, this isn't a real issue.) Completely cleaning the tree (or at least `make clean toolchain/clean`) is necessary to get a consistent state after the binutils plugins support patch and this one (as trying to use gcc-{ar,nm,ranlib} with a binutils built without plugin support will definitely lead to a build failure).
