Log:
  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.
