[PATCH] Kill warnings, fix test-tgmath on sparc64

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

This patch kills a bunch of warnings and does not define sqrt* nor fdim*
if __NO_MATH_INLINES is defined.
I've tested current CVS on i386/i686/alpha/alphaev6 without problems, ia64
is running ATM, sparc64 failed due to the issues below and because a linker
error on test-ildoubl (but that's not glibc fault and when I fixed ld it
worked).

	* sysdeps/pthread/pt-initfini.c (call_initialize_minimal): Add
	__pthread_initialize_minimal prototype.

	* sysdeps/generic/setenv.c (unsetenv): Remove const from len.
	* sysdeps/sparc/fpu/bits/mathinline.h (sqrt, fdim): Don't define if
	__NO_MATH_INLINES.
	* sysdeps/i386/dl-machine.h (elf_machine_rel): Only declare refsym
	if not RTLD_BOOTSTRAP.
	* sysdeps/sparc/sparc32/dl-machine.h (elf_machine_rela): Likewise.
	* sysdeps/sparc/sparc64/dl-machine.h (elf_machine_rela): Likewise.
