lib/libc/sys/t_mincore:mincore_resid test failing on i386

[Andreas Gustafsson <gson%gson.org@localhost>]

The mincore_resid test case of the lib/libc/sys/t_mincore test
recently started failing on i386.  It still works on amd64.

The commit that broke it was made some time during the period of build
breakage that started at CVS date 2012.04.19.17.25.38 and ended at
2012.04.21.01.15.13.

For the list of commits in that period, see:

Any ideas which commit broke it?
