Configure fails on 32-bit platform

  Configure seems to be misdetecting this 32-bit platform. The machine
  is CentOS 6, i686 .
  
  The environment is:
  
      PKG_CONFIG+PATH: /usr/local/lib/pkgconfig
       CPPFLAGS: -I/usr/local/include -DNDEBUG
         CFLAGS: -g2 -O2 -m32 -march=native -fPIC
       CXXFLAGS: -g2 -O2 -m32 -march=native -fPIC
        LDFLAGS: -L/usr/local/lib -m32 -Wl,-R,/usr/local/lib
  -Wl,--enable-new-dtags
         LDLIBS: -ldl -lpthread
  
   Then:
  
      $ ./configure
      ...
  
      configure: error: Oops, mp_limb_t is 32 bits, but the assembler code
      in this configuration expects 64 bits.
      You appear to have set $CFLAGS, perhaps you also need to tell GMP the
      intended ABI, see "ABI and ISA" in the manual.
  
      $ uname -a
      Linux localhost.localdomain 2.6.32-696.20.1.el6.i686 #1 SMP Fri

Please read the helpful message from GMP's configure, which you quoted
above.
