--- Comment #2 from Kazumoto Kojima <kkojima at gcc dot gnu.org> ---
Native TLS support is a mixture of supports in compiler, assembler&linker
and libc.  Unfortunately current native SH TLS support of linker and libc
is only for little-endian.  Binutils can work with luck.  Glibc nptl may
need a fare amount of work for big-endian TLS support.
