[Buildroot] [PATCH 1/2] package/ccrypt: fix getopt_long check for cross-compilation

[Shubham Chakraborty]

When cross-compiling, the AC_RUN_IFELSE check for getopt_long argument
reordering in configure.ac fails and defaults to "no". This forces the
build to use a stale bundled version of GNU getopt from the late 90s.

This bundled code conflicts with modern C standards (C23/GCC 15):
  - The bundled getopt.h declares getopt() with empty parentheses, which
    modern compilers interpret as (void). This conflicts with the 3-arg
    prototype in system headers like musl's unistd.h.
  - The bundled getopt.c declares getenv() with zero arguments but calls
    it with a string, causing a compiler error.

    Since all toolchains supported by Buildroot provide a working
    getopt_long, default to have_getopt_long=yes when cross-compiling.

    Set CCRYPT_AUTORECONF = YES to apply the changes to configure.ac.
