[Debian-med-packaging] Bug#834862: hisat2: FTBFS on non-x86: -msse2 (and often -m32) unrecognized

[Aaron M. Ucko]

Source: hisat2
Version: 2.0.4-1
Severity: important
Justification: fails to build from source

Builds of hisat2 for non-x86 architectures failed due to its usage of
-msse2, and in some cases also -m32.  Even where supported, these
options can limit portability, or in the case of -m32, select the
wrong ABI.

  g++: error: unrecognized command line option ‘-m32’
  g++: error: unrecognized command line option ‘-msse2’

Could you please take a look?

Thanks!
