When building the hardened kernel on a uclibc system (experimental hardened profile and stages) the build results in a symbol collision error. Reproducible: Always Steps to Reproduce: 1. Install uclibc stage3 on x86 2. Install hardened-sources and compile them 3. Build errors out Actual Results: mint linux # make -j2 && make -j2 modules_install make[1]: Nothing to be done for `all'. make[1]: Nothing to be done for `relocs'. CHK include/linux/version.h CHK include/generated/utsrelease.h CALL scripts/checksyscalls.sh CHK include/generated/compile.h CHK kernel/config_data.h make[3]: `arch/x86/realmode/rm/realmode.bin' is up to date. CHK include/linux/version.h make[2]: Nothing to be done for `all'. make[2]: Nothing to be done for `relocs'. HOSTCC Documentation/accounting/getdelays Documentation/accounting/getdelays.c:54:7: error: 'stime' redeclared as different kind of symbol /usr/include/time.h:308:12: note: previous declaration of 'stime' was here make[2]: *** [Documentation/accounting/getdelays] Error 1 make[1]: *** [Documentation/accounting] Error 2 make[1]: *** Waiting for unfinished jobs.... make: *** [vmlinux] Error 2 Expected Results: Successful kernel build. Configuration for the kernel being built (shouldn't make much of an impact) is attached in case it's useful. Let me know what else I can provide to help track this one down.

Forgot to mention versions: * sys-kernel/hardened-sources-3.5.4-r1 * sys-libs/uclibc-0.9.33.2-r2 Let me know if there is anything else I can provide to help track this down.
Okay hit it.

Created attachment 330474 [details, diff] Upsream patch to remove useless declarations of stime and utime
This is not hardened specific, so I'm dropping hardened@ and sending it kernel@'s way. @Alex. Do you mind testing the patch. Just apply it to the kernel tree, whether dirty or not, and continue building with `make -j2`.
The patch was accepted upstream: http://www.spinics.net/lists/linux-doc/msg07380.html
