defined __NO_LONG_DOUBLE_MATH
used to be
defined __UCLIBC_HAS_LONG_DOUBLE_MATH__
at line 138.

This change excludes all long double functin defs:

# make ARCH=i386
  CC libm/nan.o
libm/nan.c:49: error: 'nanl' undeclared here (not in a function)
libm/nan.c:49: warning: type defaults to 'int' in declaration of 'nanl'
libm/nan.c:50: error: 'nanl' redeclared as different kind of symbol
libm/nan.c:49: error: previous declaration of 'nanl' was here
make: *** [libm/nan.o] Error 1


I assume somebody forgot the !:

!defined __NO_LONG_DOUBLE_MATH

I will add it. If it's wrong, let me know.
