PATCH 1/1 scalb.3: fix prototypes for scalbf and scalbl

The prototypes for scalbf and scalbl given in scalb.3 are incorrect. If you have doubts, try compiling the following code:

  #include <math.h>
  double scalb(double x, double exp);
  float scalbf(float x, double exp);
  long double scalbl(long double x, double exp);

To gain confidence that the prototypes below are correct, compile the following:

  #include <math.h>
  double scalb(double x, double exp);
  float scalbf(float x, float exp);
  long double scalbl(long double x, long double exp);

Or search for man pages from other sources, e.g.:

http://www.unix.com/man-page/OpenSolaris/3m/scalbf/
http://docs.oracle.com/cd/E26505_01/html/816-5172/scalb-3m.html

The patch below fixes these mistakes.

Thanks,
Mark
