Bug#909740: libsdl2-dev: No longer multi-arch co-installable

[Hugh McMaster]

Package: libsdl2-dev
Version: 2.0.8+dfsg1-2
Severity: normal
Tags: patch

Dear Maintainer,

The package libsdl2-dev is no longer multi-arch co-installable,
as the Multi-Arch: same marking was removed in the most recent
release.

This was because SDL_config.h is no longer byte-for-byte
identical across architectures.

Unfortunately, the removal of the multi-arch marking affects
packages such as Wine, which require multi-arch support from
libsdl2-dev.

The attached patch moves SDL_config.h to /usr/include/<triplet>,
which is a far better solution. Note that this path is one of
the default search paths for headers.
