[trac558] Fix minor platform-dependent issues

Fixes two issues:
1. src/lib/log/Makefile.am referenced a now-deleted file - this
   caused issues building the logging code on some platforms.
2. The message compiler used ctime_r(), which causes a problem on
   Solaris, which implements a non POSIX-compliant version (it has
   a third argument).  As the compiler is not multi-threaded, it
   was replaced with a call to ctime().
