2003-02-25 Steven Munroe <sjmunroe@us.ibm.com>
        * elf/elf.h: Add new R_PPC64_* relocs for TLS.
        * elf/tls-macros.h [__powerpc64__]
        (TLS_LE, TLS_IE, TLS_LD, TLS_GD): Define.
	* sysdeps/powerpc/powerpc64/elf/configure.in: New file.
	* sysdeps/powerpc/powerpc64/elf/configure: New file (generated).

        * sysdeps/powerpc/elf/libc-start.c (__libc_start_main):
	Do DL_SYSDEP_OSCHECK here, matching 2002-12-01 change to generic file.
