Details:
Certain tests assume that make builds prerequisites in a specific order.
E.g. test features/se_explicit.diff.13 assumes that makes builds prerequisite
2.x before 1.x.

----
This happens, because when second expansion is enabled, snap_deps obtains the
list of prerequisites from hash_dump.
Those filenames hash to different buckets on different architectures and this
causes make to process prerequisites in the order determined by hashing.
i observed these failures on big endian sparc-sun and powerpc-aix
This patch uses prerequisite names intentionally chosen to hash in the same
order on both little and big endian.
Tested on big endian sparc-sun and powerpc-aix and little endian intel-linux,
all in 64 and 32 bit modes.
Some other tests assume that make removes intermediate files in a specific
order.
