    curl-functions.m4: remove inappropriate AC_REQUIRE
    
    AC_REQUIRE means "if this macro hasn't been executed already, execute
    it".  So in a wrapper around AC_RUN_IFELSE, AC_REQUIRE(AC_RUN_IFELSE)
    isn't correct at that will execute AC_RUN_IFELSE without any arguments.
    
    With autoconf 2.69 this is basically a no-op, but with autoconf 2.70,
    AC_RUN_IFELSE without a default value when cross-compiling is fatal.
    The result is that curl with autoconf 2.70 cannot cross-compile.
    
    Fixes https://github.com/curl/curl/issues/5126
    Closes https://github.com/curl/curl/pull/5130
