fix "tkill" check
An earlier patch removed the check for "syscall" since the results
were not used in the C code. However, the result was used, via the
cache variable, elsewhere in configure.
This patch fixes the problem by checking for "syscall" at the point at
which HAVE_TKILL_SYSCALL is defined.

* config.in, configure: Rebuild.
* configure.ac (HAVE_TKILL_SYSCALL): Check for "syscall".
