[JOB] safecat

Hi,

safecat doesn't compile because it is using errno without #include'ing
<errno.h> in some files.  This is trivial to fix.

Also, one should look in the various helper scripts like "makelib"
if the GNU architecture should be added (with similar config as GNU/Linux).

Thanks,
Marcus
