soft-float test fails on gcc 4.4

[Andrei Borzenkov]

I noticed on CentOS

address@hidden ~]# gcc --version
gcc (GCC) 4.4.6 20120305 (Red Hat 4.4.6-4)

gcc: unrecognized option '-Xclang'
gcc: unrecognized option '-Xclang'
gcc: unrecognized option '-no-implicit-float'
configure:25075: $? = 0
configure:25082: result: -msoft-float -Xclang -msoft-float -Xclang
-no-implicit-float

Which adds this string to compiler options. Not have idea how to fix
it right now.
