Remove BROKEN_PPC_ASM_CR0 configure test.
One piece of architecture-specific code in the main configure.ac is
the powerpc test that can define BROKEN_PPC_ASM_CR0.  There's no need
to move this to a sysdeps configure script, or to work out what bug it
was testing in May 1998 to see if it's still relevant, since nothing
in the source tree now uses the results of this test.  Thus, this
patch just removes the test in question.

Not tested.

	* configure.ac (libc_cv_c_asmcr0_bug): Remove configure test.
	* configure: Regenerated.
	* config.h.in (BROKEN_PPC_ASM_CR0): Remove macro.
