    UPDATING: Not unusual side effect of the awk bug fixed in 40a925385fa6b
    
    You might not be able to build the kernel if you have an awk between Jul
    10th and today. In stable/12, more (all) platforms than -current or
    stable/13 have the first offset of the thread structure in the 0xfxx
    range, which triggers this problem. If you've updated awk, you'll likely
    need to follow the instructions here to install a fixed version before
    you'll be able to build a kernel.

+	The 20210707 awk update brought in a change in behavior. This has
+	been corrected as of d4d252c49976. Between these dates, if you
+	installed a new awk binary, you may not be able to build a new
+	kernel because the change in behavior affected the genoffset
+	script used to build the kernel. If you did update, the fix is
+	to update your sources past the above hash and do
+		% cd usr.bin/awk
+		% make clean all
+		% sudo -E make install
+	to enable building kernels again.
