Add --disable-decimal-float option to gcc-cross-intermediate/gcc-cross_4.4.2.bb
PATCH 1/1 Add --disable-decimal-float option to gcc-cross-intermediate/gcc-cross_4.4.2.bb
1. Add --disable-decimal-float option to gcc-cross-intermediate_4.4.2.bb when LIBC == uclibc and TARGET_ARCH == i[3|4|5|6]86, without it, the compilation will failed due to lack of fenv.h.

It should be disabled for all uclibc based arch/distro combo's and the change should go to gcc-<version>.inc files as in my original patch.

Yes, I agree with you.
My proposal is to keep the effect of my patch as small as possible. For I have not validated other platforms, so I can not disable it this way. I will try it as soon as possible, if it did has the same problem on other platform, I will fix the patch.
By the way, on arm, mips platform, there is no such problem. I have not figured our why it does not occur on the platforms.
