* sysdeps/powerpc/fpu/feenablxcpt.c (feenableexcept): Use
__fe_nomask_env_priv instead of __fe_nomask_env to avoid a PLT call.
* sysdeps/powerpc/fpu/fesetenv.c (__fesetenv): Likewise.
* sysdeps/powerpc/fpu/feupdateenv.c (__feupdateenv): Likewise.
* sysdeps/powerpc/fpu/fenv_libc.h (__fe_nomask_env): Rename to
__fe_nomask_env_priv and attribute_hidden.
* sysdeps/powerpc/fpu/fenv_private.h (libc_fesetenv_ppc): Likewise.
(libc_feupdateenv_test_ppc): Likewise.
(libc_feresetround_ppc): Likewise.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/fe_nomask.c
(__fe_nomask_env): Rename to __fe_nomask_env_priv and adjust
compat_symbol macro.
* sysdeps/unix/sysv/linux/powerpc/powerpc64/fpu/fe_nomask.c
