    testsuite: Use -mnofpu for rx-*-* in ieee testsuite [PR107046]
    
    add_options_for_ieee has:
        if { [istarget alpha*-*-*]
             || [istarget sh*-*-*] } {
           return "$flags -mieee"
        }
        if { [istarget rx-*-*] } {
           return "$flags -mnofpu"
        }
    but ieee.exp doesn't use add_options_for_ieee, instead it has:
    if { [istarget "alpha*-*-*"]
         || [istarget "sh*-*-*"] } then {
      lappend additional_flags "-mieee"
    }
    among other things (plus -ffloat-store on some arches etc.).
    
    The following patch adds the rx -mnofpu similarly in the hope
    of fixing ieee.exp FAILs on rx.
    
    Preapproved in the PR by Jeff, committed to trunk.
