Subject: [PATCH] Fix e500 __fe_nomask_env use of __set_errno w/o CFLAGS-libm
Since the new _LIBC guard in 96c9a8f7d00cdf6bb7968a2390b9d87da8a45e2d we need
to use CFLAGS-libm (-DNOT_IN_libc -DIS_IN_libm) or we end up with linker
errors like:
lib/libm.a(fe_nomask.os): In function `__fe_nomask_env':
fe_nomask.c:(.text+0x26): undefined reference to `__libc_errno'
collect2: ld returned 1 exit status

Subject: [PATCH] Fix e500 fpu libm build
Define libm_ARCH_fpu_OUT in libm/powerpc/e500/Makefile.arch as it is used
in libm/powerpc/e500/fpu/Makefile.arch
libm_ARCH_OBJ:=$(patsubst $(libm_ARCH_fpu_DIR)/%.c,$(libm_ARCH_fpu_OUT)/%.o,$(libm_ARCH_SRC))
This appears to have been broken since cd3a494e99fa4bcad1c2a621b71361005528bead
