I implemented fabsl(3), which is what libstdc++ complained about.  We
could also get by simply by adding

#ifdef __GNUC__
#define fabsl(x) __builtin_fabsl(x)

to src/lib/msun/src/math.h.

I tried to raise interest on the -standards list a few months ago for
implementing the "long double" versions of the standard math routines,
as mandated by C99 and SUSv3, but nobody took my bait.  I also managed
to trash the partial implementation I did have, so all I have right
now is fabsl(3).
