    bpf: accept # as an inline comment char
    
    This little patch makes the BPF assembler accept '#' as an inline
    comment character, which clang -S seems to use.
    
    gas/
            * config/tc-bpf.c (comment_chars): Add '#'.
            * doc/c-bpf.texi (BPF Special Characters): Add note that '#' may
            be used for inline comments.
