	If we built POST on PPC's that didn't enable CONFIG_SYS_POST_FPU we'd get the following warning with newer toolchains: powerpc-linux-gnu-ld: Warning: lib_powerpc/fpu/libpostpowerpcfpu.o uses hard float, libpost.o uses soft float We actually worked around this sometime ago with the following commit: commit ce82ff05388b5ddafdf6082ef0776cce72c40b1c Author: Yuri Tikhonov <yur@emcraft.com> Date: Sat Dec 20 14:54:21 2008 +0300 FPU POST: fix warnings when building with 2.18 binutils However, this only took into effect if CONFIG_SYS_POST_FPU was enabled. We can simply move the GNU_FPOST_ATTR out of the CONFIG_SYS_POST_FPU ifdef block to address the issue. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
