The rest of "long double" functions aren't compiled with long double
and double are not the same. Do the same for all complex functions.

Thanks. I can confirm that the m68k, sh, and nios2 build with this patch
applied.
Hopefully Corinna or Jeff can confirm this patch can be committed.
I don't know what would be the ideal solution since long double support can
disappear within an architecture based on a multilib variable. The initial
addition of support didn't address below the architecture level.
