  libm: Include float.h to get LDBL_MANT_DIG
  
  The long double aliases of double functions are only exposed as aliases
  if LDBL_MANT_DIG is 53 (same as DBL_MANT_DIG).  Without float.h
  included these files were not exposing weak aliases as expected,
  leading to link failures if programs use the *l functions.  This should
  fix editors/calligra on targets with 64-bit long double, which uses
  erfl and erfcl.  Found on powerpc64.
