[distcc] Fix for configure.ac

[Frerich Raabe]

Moin,

right now the configure.ac file contains a bug: when checking for the
hstrerror function in libresolv, it attempts to avoid unresolved symbols
while linking with libresolv by linking two other libraries in; the relevant
autoconf method is described here:

http://www.gnu.org/manual/autoconf/html_node/autoconf_43.html#SEC43

Unfortunately, there is a comma missing, so right now the resulting configure
script will try to execute "-lnsl -lsocket" instead of passing it to the
linker. The attached patch fixes that.
