It requires a pretty fancy C++ feature and guesses whether you support
it by itself... our PLIST-guessing isn't clever enough.

# fiber requires thread_local support, unavailable in older compilers
# (old darwin, netbsd <6). if fiber becomes necessary, set GCC_REQD
# on other boost-* packages, too.
# fiber requires context, so also disable it where context cannot be built
# Additionally fiber checks std::timed_mutex.
