build-sys: rewrite TLS detection
* use more robust tls.m4 from gcc project
The old version (from util-linux-ng) used AC_TRY_COMPILE. That's
wrong. We need to use AC_RUN_IFELSE to check that the result is
link-able and executable.
The new version also test it TLS really works in multi-thread
applications.
* we need to detect TLS usability for cross-compiling
* this new version supports __thread keyword only, it seems that we
needn't to care about anything other
