*-elf-gcc compilers are generally not set up to build normally
applications, but rather low-level components like kernels and
bootloaders. Typically, you want to use a compiler that has the OS
and/or libc name in place of elf. But if this compiler works for other
applications, then perhaps that's not the case here.

I would drop the --build option unless you actually need it.

Did you see `config.log' for more details?
