configure: unset interfering variables
The check for big or little endianness relies on grep reporting match/non-match on the generated binary. If the user specified --binary-files=without-match in their GREP_OPTIONS, this will fail. Let's follow what autoconf does and unset GREP_OPTIONS and CLICOLOR_FORCE at the beginning of the script.
