Subject: [PATCH] Fix cross compiling the uuid module

Python 3.7 has a new _uuid module, however, the include directory
search path for uuid.h is hardcoded to /usr/include/uuid, which should
not be used when cross-compiling.

To fix this, use the same solution as the one used by the NIS
detection: append "uuid" to each of the include directories in
"inc_dirs", instead of hardcoding /usr/include/uuid.

[Thomas: drop STAGING_DIR based solution, use a solution similar to
the one used for the NIS detection.]
