Alignment-specific tests fails on i386

[nmeum]

On i386 the tests fail (I ran into this with Guile Scheme):

$ make check
./pre-inst-env          \
  /usr/bin/guile --no-auto-compile              \
  ./run-tests.guile.scm

The following test case fails:

My educated guess is that this because bs is not a packed struct and the way bs is packed on i386 differs from other architectures. Since the test is—as is—not portable it would probably be best to remove it?
