Just to report in: I do not have this problem, and am able to build minocaOS clean on my macOS rig.

Gcc output:

looks like libc/time.h in not included (but another one is found?), however the include config seems correct: https://github.com/minoca/os/blob/master/apps/swiss/Makefile#L30-L32

Swiss is another case of a utility that is built for both the build machine and Minoca. Looks like we're failing to build for the build machine.
My main GCC comes from xcode 8.0 (8A218a), and it's really clang pretending to be GCC:

It looks like clock_gettime and CLOCK_MONOTONIC were only very recently added to macOS. They're in my 10.12 SDK, but I'm wondering if you've got a slightly older one. I'm not a mac guru, but it strikes me as weird that I'm building on a 10.12 SDK while running 10.11.6. Does that mean this GCC may not be able to run the programs it produces?
@aequitas What built-in include paths do you have? Slightly older SDK? If you're willing to download the latest SDK, that might be a fast workaround. I'll also start looking at alternate functions we can call on macOS.

@evangreen thanks for pointing out how to verify the gcc environment, from what I can see I am missing the MacOSX SDK includes on clang as well as gcc-6. I will try to find out why. The SDK with content is present, but just not found by clang/gcc it seems.

I resolved my issues by exportingSDKROOT=$(xcrun --show-sdk-path). I don't know if that is the recommended/required way or that I messed up my Xcode in the past (did a full reinstall with no result).
I now have successfully built a x86 pc.img have not tested it yet, still need to figure out if armv6 cross-compiling works as well now.

Thanks @aequitas . I've made a note of your SDKROOT fix in the readme.
Sounds like this bug is fixed. Last call?

I consider this problem solved, I am able to build an image. I still need to test for armv6 and test it on my hardware, but I have no reason to expect it doesn't run. If I run into issues there I will (re)open an issue. Thanks for the support, I have been looking for a while for a OS like Minoca, I'm curious if it fits my need.
One minor thing that doesn't work yet is a 'rel' build:
Compiling - bconf.c
error: unknown warning option '-Wno-unused-but-set-variable'; did you mean '-Wno-unused-const-variable'?
[-Werror,-Wunknown-warning-option]
make[6]: *** [bconf.o] Error 1
make[5]: *** [build] Error 2
make[4]: *** [bconflib] Error 2
make[3]: *** [/Users/johan/Projecten/minoca/armv6rel/obj/os/lib] Error 2
make[2]: *** [tool-build-libc] Error 2
make[1]: *** [/Users/johan/Projecten/minoca/armv6rel/obj/third-party/gcc-4.9.2.tool/build.stamp] Error 2
make: *** [/Users/johan/Projecten/minoca/armv6rel/tools/bin//arm-none-minoca-gcc] Error 2
which seems due to: https://github.com/minoca/os/blob/master/minoca.mk#L208
for now I just build dbg, and this should be easy to work around if I want a rel, so its just as FYI.
