Since glibc 2.17, executable link command need not include the -lrt option for clock_* system calls. As a result, over time less and less software packages bother to check whether to toolchain needs -lrt. We are now at a point where maintainers refuse to add this complexity into their build system. This requires Buildroot to carry patches fixing this issue indefinitely. glibc 2.17 is now 4.5 years old. There is no reason to use an older version with current software. This commit removes the predefined profile for CodeSourcery x86 toolchain that is based on glibc 2.16. One may still use the custom external toolchain support in Buildroot to get this toolchain back, and deal with any build issues that this toolchain causes.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
