Comment(by tornaria):
Looks good to me.
For the record, I want to point out that mpir may be using {{{lahf}}}
flag, which is ''not'' among the tested-for flags. Note that {{{lahf}}}
does not depend on {{{ssse3}}} (e.g. a Pentium D 930 has {{{lahf}}} but
not {{{ssse3}}}). Apparently the first intel 64 bit cpus did ''not'' have
{{{lahf}}}.
