No it isn't. I already reported this to perl5-porters.
The problem is that the signal names are defined in a different include
file since somewhere in the 1.3.x kernel series.

The fix is to change a bit of the perl Configure script to read

echo "Generating a list of signal names..." >&4
xxx=`./findhdr signal.h`" "`./findhdr sys/signal.h`
xxx="$xxx "`./findhdr linux/signal.h`" "`./findhdr asm/signal.h`
^^^^^^^^^^^^^^^^^^^^^^^^^^
