Assembly code not working for mips64el and ppc64el (Was: Bug#972004: bowtie ftbfs on several release architectures)

Control: tags -1 help

Hi,

while I've fixed the issue for arm64 the new version of bowtie seems to
have some new assembly code where mips64el, ppc64el and others are
stumbling upon [1]:
