[Debian-med-packaging] Bug#784780: subread: FTBFS on non-x86: unrecognized command line option '-msse3'

[Aaron M. Ucko]

Source: subread
Version: 1.4.6-p2+dfsg-1
Severity: important

Builds of subread on non-x86 architectures have been failing:

  gcc: error: unrecognized command line option '-mmmx'
  gcc: error: unrecognized command line option '-msse'
  gcc: error: unrecognized command line option '-msse2'
  gcc: error: unrecognized command line option '-msse3'
  <builtin>: recipe for target 'core.o' failed
  make[2]: *** [core.o] Error 1
  make[2]: Leaving directory '/«BUILDDIR»/subread-1.4.6-p2+dfsg/src'

Most of these architectures (except arm64, for some reason) also
reject -mtune=core2.  Could you please fully retire the use of -mmmx
and -msse*, which aren't appropriate even on x86 because they yield
binaries that will encounter "illegal instruction" errors on older
hardware, and either do the same for -mtune=core2 or at least restrict
it to x86 as well?

Thanks!
