    testsuite: Skip target not support -pthread [PR104676].

    The "ftree-parallelize-loops=" imply -pthread option in gcc/gcc.cc,
    some target are not support pthread like elf target use newlib,
    and will get an error:

    "*-*-elf-gcc: error: unrecognized command-line option '-pthread'"

    so we add an additional condition "{target pthread}" to make sure the
    dg-additional-options runs on support targets.
