The following patchset implements 3 seperate series of changes. External Building ================= Patches 1 through 8 enable to use of klibc's build system while leaving the src tree pristine (and potentially read only). Specifically: - srctree=<Sources for klibc> - objtree=<Ouput directory for klibc> - KLIBCKERNELSRC=<Kernel sources> - KLIBCKERNELOBJ=<Kernel

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code. This is also available as a git tree at:
