Passing CC="gcc -m32" fixes 32bit build.

64bit build is more problematic -m64 is used by default so no need to
set CC. I've configured with --build=x86_64 but generated makefile was
wrong. I had manually to add XCC = gcc (was empty) and path to
libsigsegv installation to XCPPFLAGS. At the end I got to:
Undefined symbols:
  "_libiconv", referenced from:
      _oconv_unshift_output_buffered_ in stream.o
      _oconv_unshift_output_unbuffered_ in stream.o
..........
Looks like 64bit version of libiconv does not export libiconv() function.
