libc6: improve reproducibility

Building various libraries (libc6, libc6-pic, libc6-staticdev, libc6-dbg, ...)
can be non-deterministic because they may be built with two different versions
of intl/plural.c. in two otherwise identical builds. We may or may not re-generate
the file plural.c from the file plural.y, based on bison being installed or not
and based on mtimes of those two files, as the Makefile contains:

plural.c: plural.y
$(BISON) $(BISONFLAGS) $@ $^

If the above rule does not fire, we use a "fallback" plural.c, otherwise
we use plural.c re-generated from plural.y.
The fix is to always require bison to be installed and unconditionally
re-generate plural.c. (This is achieved by touching plural.y).
