   1 [PATCH]: use AC_TRY_LINK for stack protector check
   2
   3 Actually try to link an executable to test for stack protector support,
   4 as gcc seems to accept the -fstack-protector argument even when it's
   5 compiled with --disable-libssp (but linking fails with a error
   6 finding -lssp_nonshared).
