What -O level did you compile libc with? Optimisation levels >= 2 damage
__vfprintf() with the in-tree gcc, causing these same symptoms.

The fix is to remove any optimisation options above -O, go into
/usr/src/lib/libc, rebuild and install the static libc.a, build and install a
static linked awk binary, then rebuild world + kernel as usual.
