Bug#965340: libsleef-dev: Unable to install multiple architecures due to conflicting header

[Evan Nemerson]

Package: libsleef-dev
Version: 3.4.1-2
Severity: important

Dear Maintainer,

It is not currently possible to install libsleef-dev on multiple
architectures due to all packages installing /usr/include/sleef.h.
This makes it difficult to develop software targeting multiple
architectures.

The sleef.h header is platform-specific; the x86 version has SSE
versions of various functions, ARM has NEON versions, etc.  AFAIK
that means the header should go in /usr/include/$ARCH/ instead of
just /usr/include/.

Reproducing should be trivial; just (try to) install libsleef-dev
on multiple architectures.
