Created attachment 374340 [details, diff] kbuild-uclibc.patch kbuild as is does compile on uclibc. It is due to missing defines, and because the functions lchmod (a BSD extension) and getloadavg do not exist in uclibc. I attach the build fix patch here. That does not allow to build VirtulaBox on uclibc yet

Created attachment 374344 [details, diff] kbuild-uclibc-shthread.patch This patch should not sent upstream. However, I am unable to fix the preprocessing problem leading to "#error Port me" when building shthread.c on uclibc. I only came with this ugly hack applied conditionally.
Could you report the errors you purportedly patched, please?
* Added lchmod implementation in src/kmk/kmkbuiltin/chmod.c and kmk/kmkbuiltin/cp_utils.c. * Added __UCLIBC__ conditional in src/kmk/kmkbuiltin/cp.c , src/kmk/kmkbuiltin/fts.c , src/lib/k/kDefs.h , * Added getloadavg implementation in src/kmk/job.c
Still no idea what bugs you are fixing, I just see more vague descriptions.
the lchmod call should be changed to fchmodat. the former is not in POSIX while the latter is, and both glibc/uclibc support it already.
sys-libs/uclibc has been removed from the tree, replaced by sys-libs/uclibc-ng. if this is still a problem on uclibc-ng, please open a new bug.
