    libgcc: mark __hardcfr_check_fail as always_inline
    
    The function __hardcfr_check_fail in hardcfr.c is internal and static
    inline.  It receives many arguments, which require more than five
    registers to be passed in bpf-none-unknown targets.  BPF is limited to
    that number of registers to pass arguments, and therefore libgcc fails
    to build in that target.  This patch marks the function with the
    always_inline attribute, fixing the bpf build.
    
    Tested in bpf-unknown-none target and x86_64-linux-gnu host.
    
    libgcc/ChangeLog:
    
            * hardcfr.c (__hardcfr_check_fail): Mark as always_inline.
