[libstdc++/3052] 3.0 unresolved ref to sqrtf

[Wolfgang Bangerth]

While the problem for the functions with floats has apparently been fixed
with present 3.0.1 CVS, it persists for long double functions. For the
appended small file I get linker errors complaining about missing
functions sqrtl, cosl and sinl.

Fix: probably just like for sqrtf, cosf and sinf.
