                ^^^^^^^

I worked around this part of the problem since I realised that upstream
simply is adding a code copy of cpuid.h which is from some old gcc
version.  While I was hoping that simply removing

    -I third_party

from the build system would help I learned that this only leads to other
problems[1].

  1. it seems with the exception of i386 other architectures do not even seem to
     have this include file:

	processor_support.h:17:22: fatal error: cpuid.h: No such file or directory
	#   include <cpuid.h>


  2. i386 results in

	ebwt.h: Assembler messages:
	ebwt.h:1909: Error: invalid instruction suffix for `popcnt'
	ebwt.h:1909: Error: invalid instruction suffix for `popcnt'
	ebwt.h:1909: Error: invalid instruction suffix for `popcnt'
	ebwt.h:1909: Error: invalid instruction suffix for `popcnt'
	make[2]: *** [bowtie-build] Error 1

     The relevant line in the code is:

	$ grep -w -n  asm e*
	ebwt.h:1909:            asm ("popcntq %[x],%[count]\n": [count] "=&r" (count): [x] "r" (x));


Any help would be welcome - otherwise the package (and its rdepends) need
to be restricted to amd64 architecture.

Kind regards

        Andreas.
