>Description:

When perl with thread support is enabled, using "perl -MExtUtils::Embed
-e ldopts" outputs a suggestion for linker options with -lc as one of
the libraries. This is incorrect.  Linking stuff with both -pthreads and
-lc results in the program segfaulting when dup2() (and I'm sure other
functions as well) is invoked.

>How-To-Repeat:

make world with PERL_THREADED enabled, then make the news/inn
port.  innd when started will segfault while doing a dup2().

>Fix:

remove the -lc from the libs= line in the files
src/gnu/usr.bin/perl/libperl/config.SH-threads*
Or, alternatively, change -lc to -lc_r

(Also, note that the "Target system" comment is slightly out of date for
many config files in that directory on both current and stable.  Perhaps
it'll be easy to just say FreeBSD?)
