Relocate alpha from ports to libc

Also fixed the following whitespace nits to satisfy the push:

sysdeps/alpha/alphaev6/memset.S:142: space before tab in indent.
sysdeps/alpha/configure:1: new blank line at EOF.
sysdeps/alpha/fpu/e_sqrt.c:126: space before tab in indent.
sysdeps/alpha/preconfigure:1: new blank line at EOF.
sysdeps/unix/sysv/linux/alpha/syscalls.list:1: new blank line at EOF.

- *    $9-$14 we save here (s0-s5);
- *    $15 is the FP and we save it here (fp or s6);
- *    $16-$21 are input arguments (call-used) (a0-a5);
- *    $26 is the return PC and we save it here (ra);
- *    $27 is the procedure value (i.e., the address of __setjmp) (pv or t12);
- *    $29 is the global pointer, which the caller will reconstruct
- *        from the return address restored in $26 (gp);
- *    $30 is the stack pointer and we save it here (sp);
- *    $31 is always zero (zero).
- *
- * Floating-point registers:
- *    $f0 is the floating return value;
- *    $f1, $f10-$f15, $f22-$f30 are call-used;
- *    $f2-$f9 we save here;
- *    $f16-$21 are input args (call-used);
- *    $f31 is always zero.

- * Note that even on Alpha hardware that does not have an FPU (there
- * isn't such a thing currently) it is required to implement the FP
- * registers.
