Fix printing of long doubles to match the size that

gcc is using.  This fixes devstat consumers (like vmstat, iostat,
systat) so they don't print crazy zillion digit numbers for
disk transfers and bandwidth.

According to gcc, long doubles are 64-bits, rather than 128 bits
like the SVR4 ABI spec wants them to be..  Note that MacOSX also treats
long doubles as 64-bits, and not 128 bits, so we are in good company.
