Subject: BUILD: signals: FreeBSD has SI_LWP instead of SI_TKILL
X-Git-Tag: v2.0-dev5~91

BUILD: signals: FreeBSD has SI_LWP instead of SI_TKILL

SI_TKILL is for Linux. We're again in the non-portable area. Both OSes
use macros to define these values so we can #ifdef them. Let's make
SI_TKILL defined based on SI_LWP when only the latter is defined.
