<pre>This is what I get when building on a x86_64 cpu to generate the x86 32bit

Other backends build fine.
Here is the script (important part) I use to launch the build (it's part of a
PKGBUILD file I'm trying to port from autotools to cmake):
build() {
_cpucount=$(grep -c processor /proc/cpuinfo 2>/dev/null)
_jc=$((${_cpucount:-1}))
cd "${srcdir}"
mkdir -p build
cd build
export CC="gcc -m32"
export CXX="g++ -m32"
export PKG_CONFIG_PATH="/usr/lib32/pkgconfig"
# Apply strip option to configure
_optimized_switch="enable"
[[ $(check_option strip) == n ]] && _optimized_switch="disable"
# Include location of libffi headers in CPPFLAGS
CPPFLAGS+=" $(pkg-config --cflags libffi)"

Am I missing something or is the AMDGPU backend not taking into account the
target architecture right now?
P.S.: it seems at least "Backend: AMDGPU" and "Backend: Hexagone" are missing
from the component list.</pre>
