    testsuite: Fix gdb.btrace/tailcall-only.exp errors on x86_64-m32
    
    $ runtest 'CC_FOR_TARGET=gcc -m32' gdb.btrace/tailcall-only.exp
    Running ./gdb.btrace/tailcall-only.exp ...
    gdb compile failed, tailcall-only.c: Assembler messages:

    I'm setting the target triplet to "i686-unknown-linux" in my m32 configuration.
    Like this:

    set_board_info cflags "-m32"
    set_board_info cppflags "-m32"

    There's no reason you should _not_ set it.
    
    But, multilib-style testing with --target_board=unix\{-m64,-m32\} etc.
    should work _too_, IMO.
