gold patch: use strict prototypes with .c files

[Craig Silverstein]

My compiler seems to add -Wstrict-prototypes and -Wmissing-prototypes
by default when compiling C files.  This was causing a few C-language
gold tests to fail.  The fix is easy enough.  If I were a more
confident gold developer, I might submit these as obvious. :-)  As it
is, can someone approve them?

--cut here--

      * tls_test_c.c: Add prototype for t11 and t11_last.
      * tls_test_c.c (t11): Add explicit "void" to prototype.
      (t11_last): Likewise.
      * ver_test_6.c (main): Likewise.
