System libm doesn't provide C99 long double math routines.

--- Comment #1 from John David Anglin <danglin at gcc dot gnu.org> ---
Although there is support for long doubles on this target, it lacks the
long double math functions added in c99.  So, it doesn't have fabsl.

There is a libcall implementation of abs for long double and the test
passes the execution test since fabsl is folded to a built-in.  However,
I couldn't suppress the "incompatible implicit declaration of built-in
function"
warning.  So probably, it's best to either explicitly disable test or
require c99.
