[Skiboot] [PATCH v2 01/19] Makefile.check: Fix `make check`

[Cyril Bur]

Recent reworks were tested on the travis-ci system. Unfortunately, there
are configurations of running `make check` which the travis-ci doesn't
do. On some systems extra problems crop up.

Removing the stack size check is only done for the host compiler as the
check is only critical for skiboot its self where stack space is
contained.
