Bug#1052382: sysprof: Should not build-depend on libunwind-dev on unsupported architectures

[John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de>]

Source: sysprof
Version: 45.0-1
Severity: normal
User: debian-68k@lists.debian.org
Usertags: m68k

Hello!

src:sysprof build-depends on libunwind-dev unconditionally despite the fact that libunwind
is not available on the following architectures:

- alpha
- arc
- hurd-i386
- m68k
- sparc64
- x32

NB: While libunwind is currently not built on loong64, upstream support is already present
    and it's therefore expected that libunwind will be available on loong64 in the near
    future.

Can you please disable libunwind for the architectures mentioned above?

Thanks,
Adrian
