[klibc] alpha: Support building without glibc headers

Unless we use the "-nostdinc" option, gcc will implicitly include
<bits/stdc-predef.h>, which is usually provided by glibc.  This is
part of $(KLIBCCPPFLAGS) which we generally include in compiler
command lines.  Add it to alpha's special rules for compiling the
division subroutines.
