Summary:
The sys/cdefs.h in src is incompatible with glibc's sys/cdefs.h so
cross-building broke when the former was added to SYSINCS in 1c9ff80f06. This
commit adds a guard around that to only do that when building on FreeBSD. This
should fix github CI.
Test Plan:
Ran buildkernel using tools/build/make.py on linux in github CI and
locally on FreeBSD to double check nothing broke.

Don't split the error messages across lines. We used to do that ages
ago, but have relaxed style(9) to encourage the opposite so all error
messages can be grepped. This constantly slows me down when I'm helping
others find issues, so start here by splitting according to normal
style(9) rules with a relaxed line length of 90.

There are many environments that you do not want the paths to be
canonicalized. For example, if I always build a product from a specific
path in a jail that's dependent on the product version, I don't want
that to be sanitized to /usr/src because when I have profiling tools run
against multiple kernels, I can't do A/B testing and results processing
if everything points to /usr/src (sadly, the profiling tools cannot
remap back to the original like gdb can). Since we need both active at
the same time, symbloic link fallbacks don't work.
We do want the rest of the build to be reproducible, however. We'll get
the same binaries if we rebuild later since we always rebuild with the
same path.
Turn them both on for maximum reproduction for environments where that
cannot be guaranteed.

Fix powerpc 64 little endian booting by adding some padding. Due to
https://gitlab.com/slof/slof/-/blob/master/lib/libelf/elf32.c?ref_type=heads#L114https://gitlab.com/slof/slof/-/blob/master/lib/libelf/elf32.c?ref_type=heads#L150
using <= instead of <, slof used to loop over the phdrs. It overruns by
1 and so on little endian it swizzles the first 32 bytes of .text. Work
around this by adding 32 bytes of padding after the headers. We should
fix this in slof, but it's in the just released QEMU 10.2, so we have to
pad things here for now.
Now powerpc64le + qemu works.

If we're sending a packet via pf_route()/pf_route6() we check for packet
size and potentially generate ICMP(6) packet too big messages. If we do,
don't consider this a rejected packet. That is, return PF_PASS and set
the mbuf to NULL rather than returning PF_DROP.
This matters for locally generated packets, because with PF_DROP we
can end up returning EACCES to userspace, causing the connection to
terminate. Instead, with PF_PASS and a NULL mbuf this is translated to
PFIL_CONSUMED, which does not return an error to userspace.
