[Buildroot] [git commit master] iperf: override bool detection

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=e13ac0ec8788092c6508636da94fe0198c18dffd
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The configure script contains a buggy test for the bool datatype and
it's size. This is normally not a big deal as the result isn't used
for anything, but when BR2_CONFIG_CACHE (default) is used, the
wrong ac_cv_type_bool result is stored in the cache, and other packages
like libcurl DO need the bool type, so that breaks the build.

Fix it by presetting those tests to sane values.
