Bug#907912: llvm-toolchain-7: Please disable libomp on unsupported architectures

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

Source: llvm-toolchain-7
Version: 1:7~svn331965-1
Severity: normal
User: debian-sparc@lists.debian.org
Usertags: sparc64

Hi!

llvm-toolchain-7 currently fails to build from source on the
following architectures because the embedded libomp doesn't
support them:

 - powerpc
 - powerpcspe
 - riscv64
 - sparc64

And possibly:

 - armel
 - mips
 - mipsel

Although the latter three might be fixable by linking against
libatomic but I haven't looked into the details yet. Either way,
disabling libomp for the former four architectures or, better,
enabling it for supported architectures only, should fix the
FTBFS on multiple architectures.

Adrian
