- fabsl.c should be named s_fabsl.c for consistency with libmsun's

   documented naming scheme (unfortunately the documentation isn't in the
   tree as far as I can tell); no repocopy is required as there is no
   history to preserve.

 - replace simple and almost-correct implementation with slightly hackish
   but definitely correct implementation (tested on i386, alpha, sparc64)
   which requires pulling in fpmath.h and the MD _fpmath.h from libc.

 - try not to make a mess of the Makefile in the process.

 - enterprising minds are encouraged to implement more C99 long double
   functions.
