r311925:
Import testcase updates with code contributed back to NetBSD
This also (inadvertently) contains an update to
contrib/netbsd-tests/lib/libc/sys/t_wait.c (new testcases).
In collaboration with: christos@NetBSD.org
r311968:
Fix lib/libc/sys/access_test after r311925
sys/param.h needs to be #included in order for __FreeBSD_version to be checked
r311969:
Remove __HAVE_LONG_DOUBLE #define from t_strtod.c and place it in Makefile
This is to enable support in other testcases
Inspired by lib/msun/tests/Makefile .

- .../lib/msun
- .../sys/kern
Tested on: amd64, i386
