  Ensure that CFLAGS and/or LDFLAGS provided to configure script are preserved.
  
  Cross-compilation environments want to provide 'defaults' for compiler and
  linker options, and frequently do this by specifying CFLAGS and LDFLAGS in the
  environment or as command-line arguments to the configure script. This patch
  modifies the configure script and Makefile to preserve these settings and
  ensure they are used in the build process.
