I guess you mean this:

x64_6432 is not the same as x64_64. It means, afaik, a 32 bit binary  
running on a 64 bit Linux system. It probably changes some default  
library search paths or so. The i386 compiler cannot generate x86_64  
binaries. The appropriate code generator is simply not available.
