patch: basic implementation of machine flag check for LoongArch

eu-elflint is unhappy about any LoongArch (lp64d ABI) ELF binary, in
particular, about itself:

$ ./src/elflint --gnu-ld ./src/elflint
invalid machine flags: 0x43
$ echo $?
1

    LoongArch: implemented a basic machine flag check

    With this patch I can use eu-elflint to verify LoongArch ELF
    binaries. Previously eu-elflint was complaining about invalid
    machine flags:

    $ ./src/elflint --gnu-ld ./src/elflint
    invalid machine flags: 0x43
    $ echo $?
    1

        * backends/loongarch_symbol.c (loongarch_init): Hook
        machine_flag_check.
        * backends/loongarch_symbol.c (loongarch_machine_flag_check):
        New function.
