Thank you Vagrant for reporting this issue and your patch.

SIMDe is a header-only library, the compilation is just to test the
library against the default GCC & clang versions in Debian. I would
prefer to keep testing the default versions, to get ahead of any bugs
that might appear.

I guess testing for all versions of clang and gcc in Debian could be
done as part of the package building and autopkgtest.

So I'm leaning towards adding the other fix of disabling setting
DEB_BUILD_MAINT_OPTIONS=reproducible=-fixfilepath+fixdebugpath

What do you think?
