emutls:
+ add support for platform-provided __emutls_get_address();
+ add support for .emutlsv and .emutlst as named sections
storing tls variable definitions and default values,
respectively. According to the documentation, this
could have also been achieved by assigning a value to
TARGET_EMUTLS_VAR_SECTION; doing so, however, resulted
in a compiler crash, so for now we are using a designated
conditional macro instead.
