Declare some functions and variables static, to pacify GCC when
warning about external functions missing declarations.

sigsegv: don’t assume SIGSTKSZ is a constant
* m4/sigaltstack.m4 (SV_SIGALTSTACK): Don’t attempt to override
SIGSTKSZ. Instead, use an array that is plenty large, while
checking that it’s large enough. Also, be consistent about
putting that array in static storage rather than on the stack.
* tests/altstack-util.h (SIGSTKSZ): Don’t define.
(MYSTACK_SIZE): New macro, used consistently instead of SIGSTKSZ.
(mystack_storage, mystack): Now static.
(prepare_alternate_stack) [defined SIGSTKSZ]:
Check that MYSTACK_SIZE is large enough.
