Fix some missed "beneath" conversions

The buildbot pointed out that arm-linux-nat.c was not properly using
"beneath" as a method.  A search showed a few more places with this
issue.

Tested by the buildbot, though of course this only checked
arm-linux-nat.c.  Nevertheless I'm checking this in under the obvious
rule.
