xcompile: Fix compiler invocation in testcc

While for GCC targets the compiler is just defined as a single
    binary, for clang it is defined as a binary and some options, e.g.:
      clang -target i386-elf -ccc-gcc-name i386-elf-gcc

When executing the compiler with "$1", the shell will look for a
    binary with the above name (instead of just clang) and always fail
    detection of any CFLAGS.

By adding -c we prevent the compiler from failing because it can't
    link a user space program (when what we're looking for, is whether
    a specific compiler flag can be used to compile a coreboot object
    file)
