configure: cache result of "sys/sdt.h" header check

Use AC_CACHE_CHECK to store the result of the header check for
systemtap's "sys/sdt.h", which is similar in spirit to libstdc++'s
AC_CACHE_CHECK(..., glibcxx_cv_sys_sdt_h).

gcc/
* configure.ac: Add AC_CACHE_CHECK(..., gcc_cv_sys_sdt_h).
* configure: Regenerate.
