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 ce82ff0538
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.
