[lttng-dev] [PATCH urcu] Fix: Fallback mechanism not working on platform where TLS is unsupported

[Christian Babeux]

The CONFIG_RCU_TLS entry in config.h.in is defined by default to "TLS".
This has the unfortunate consequence of defining CONFIG_RCU_TLS on platform
where TLS is unsupported and effectively disabling the pthread based
fallback mechanism. This macro should be #undef by default and the
AX_TLS m4 macro will properly detect if TLS is supported.
