Bug#835447: libmodule-build-withxspp-perl: please make the output reproducible

Exactly. The call to Cwd::abs_path introduces the build directory into
target:

There's a fair amount of indirection going on here as the INCLUDE_COMMAND
is actually executed later on in the build.

Simply dropping the abs_path call would not work as the typemap files are
not present within the build directory when XS actually evaluates the line.

Hope that helps.
