Subject: * sysdeps/powerpc/fpu/fenv_libc.h: Add libm_hidden_proto for

	__fe_nomask_env.
	* sysdeps/powerpc/fpu/fe_nomask.c: Add libm_hidden_def.
	* sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/fe_nomask.c: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/fpu/fe_nomask.c: Likewise.

	* sysdeps/powerpc/bits/fenv.h: Make safe for C++.

	* sysdeps/unix/sysv/linux/powerpc/bits/mathinline.h: New file.
	* sysdeps/powerpc/fpu/fegetexcept.c (__fegetexcept): Rename
	function from fegetexcept and make old name weak alias.
	* include/fenv.h: Declare __fegetexcept.
	* sysdeps/powerpc/fpu/fedisblxcpt.c: Use __fegetexcept instead of
	fegetexcept.
	* sysdeps/powerpc/fpu/feenablxcpt.c: Likewise.
	* sysdeps/powerpc/fpu/fraiseexcpt.c (__feraiseexcept): Avoid call
	to fetestexcept.
	* sysdeps/ieee754/ldbl-128ibm/s_log1pl.c (__log1pl): Use __frexpl
	instead of frexpl to avoid local PLT.
	* math/s_significandl.c (__significandl): Use __ilogbl instead of
	ilogbl to avoid local PLT.
	* sysdeps/ieee754/ldbl-128ibm/s_expm1l.c (__expm1l): Use __ldexpl
	instead of ldexpl to avoid local PLT.
	* sysdeps/ieee754/ldbl-128ibm/e_expl.c (__ieee754_expl): Use
	__roundl not roundl to avoid local PLT.
	* sysdeps/ieee754/ldbl-128/e_j0l.c: Use function names which avoid
	local PLTs.  Use __sincosl instead of separate sinl and cosl
	calls.
	* sysdeps/ieee754/ldbl-128/e_j1l.c: Likewise.
