We currently use KLIBCKERNELSRC and KLIBCKERNELOBJ variables which used to be required to point to a kernel source and object directories. However the kernel headers were reorganised starting in Linux 3.7 such that that doesn't work properly. This series removes KLIBCKERNELOBJ and changes the use and documentation of KLIBCKE...

...k really wants to be in the root of the source archive (klibc-2.0.2/linux), not in usr/ (klibc-2.0.2/usr/linux) (the dir above the one where README.klibc is found). In Kbuild.install, 'INSTALLROOT' is what many (most?) packages call DESTDIR: an alternate install dir to prepare pkgs. And KLIBCKERNELSRC is the path to the kernel sources. In my case, this is /build/sources/linux/linux-3.10.7 (in the jail). There's an oddity in how include dirs are specified. First, an absolute 'relative' dir and it's companion: -I/build/sources/klibc/klibc-2.0.2/usr/klibc/../include -Iusr/kl...
