  float: Fix LDBL_MAX value on Linux/PowerPC.
  
  * m4/float_h.m4 (gl_FLOAT_H): Set FLOAT_H and REPLACE_FLOAT_LDBL also
  on Linux/PowerPC.
  * lib/float.in.h (LDBL_MAX): Redefine also on Linux/PowerPC.
  * lib/float.c (gl_LDBL_MAX): Also define on Linux/PowerPC.
  * doc/posix-headers/float.texi: Mention Linux/PowerPC as an affected
  platform.
