Hi,

This patchset fixes a bunch of regressions introduced recently caught by
building the defconfig.

[Buildroot] [PATCH 1/3] armv8: Fix defconfig build

[Maxime Ripard]

Commit 14f48861 ("arc: Add ARC and ARC BE architecture") introduced a
sed match against arc* buildroot architecture to translate it to arc.

This causes a problem with armv8, which is called in buildroot aarch64,
which is also matching, resulting in a build failure.

[Buildroot] [PATCH 2/3] pandaboard: Fix defconfig build

[Maxime Ripard]

Commit 75b7dc68 ("linux: default to 3.9, remove 3.8") made 3.9 the
default kernel version.

The omap kernel switched to multiplatform kernel during the 3.9 kernel
development cycle. Obviously, the uImage generation doesn't work anymore
with multiplatform kernels, since you have to provide the kernel load
address, resulting in a build error.

Lock down the kernel version to 3.8 to keep the old behaviour until
someone submits a patch to switch to multiplatform kernel.

[Buildroot] [PATCH 3/3] toolchain/gcc: Enable --with-float for powerpc

[Maxime Ripard]

Commit 8d929f4b ("toolchain/gcc: Only enable --with-float when it makes
sense") restricted the --with-float use to only MIPS, ARM and SPARC,
while it seems that powerpc needs it as well.

Fixes the qemu_ppc_virtex_ml507_defconfig build.
