Bug#999866: liboqs: please make the build reproducible

[Chris Lamb]

Source: liboqs
Version: 0.7.0.27.gba5b61a7+dfsg-1
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
liboqs could not be built reproducibly.

This is because it embeds ${CMAKE_SYSTEM_PROCESSOR} and ${CMAKE_HOST_SYSTEM}
via the OQS_COMPILE_BUILD_TARGET define. Luckily, the code itself uses
an ifdef, so a patch is attached that simply prevents this being added to the
header file.
