Do not trust apr_hints.m4 for setting '-D_REENTRANT', set it only for
toolchains with thread support.
Fixes misleading configure error ([1]):
checking whether int64_t and int use fmt %d... no
checking whether int64_t and long use fmt %ld... no
checking whether int64_t and long long use fmt %lld... no
configure: error: could not determine the string function for int64_t
which results from warning (promoted to error by '-Werror=cpp'), from
config.log:
