dbus must be compiled with -D_REENTRANT option to make errno thread-safety

[Pavel Strashkin]

I'm on Solaris.
My <errno.h> makes thread-safe errno only if _REENTRANT is defined.

I see that you already have "some threads stuff" for Solaris in configure.in:
 502 # Add -D_POSIX_PTHREAD_SEMANTICS if on olaris
 503 #
 504 case $host_os in
 505     solaris*)
 506        CFLAGS="$CFLAGS -D_POSIX_PTHREAD_SEMANTICS" ;;
 507 esac

So, may be it make sence add "-D_REENTRANT" there too?
