Create a new macro for checking compiler support for TLS.
Create a new macro that can be shared between projects to check for
__thread support by the compiler. This macro might come useful for
xine-lib too so I want to keep it separate for easier importing it
over.
Name the defined macro SUPPORT_TLS___THREAD to follow the same style
as the checks from attributes.m4.
