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.

signed-off by Z. Gilboa; see copying.midipix (9cd0746c) for additional information.
