Hi Thomas,

tested a defconfig based on support/config-fragments/autobuild/br-i386-
pentium4-full.config

BR2_x86_pentium4=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y
BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.org/toolchains/
tarballs/br-i386-pentium4-full-2020.11.2.tar.bz2"
BR2_TOOLCHAIN_EXTERNAL_GCC_9=y
BR2_TOOLCHAIN_EXTERNAL_HEADERS_4_4=y
BR2_TOOLCHAIN_EXTERNAL_LOCALE=y
# BR2_TOOLCHAIN_EXTERNAL_HAS_THREADS_DEBUG is not set
BR2_TOOLCHAIN_EXTERNAL_CXX=y
BR2_PACKAGE_LIBVPL=y

libvpl build is broken:

output/build/libvpl-2.13.0/api/vpl/mfxdefs.h:75:6: error: #error Unknown 
packing
   75 |     #error Unknown packing

because the compiler does not define __ILP32__

$ i686-linux-gcc -dM -E - < /dev/null | grep -E "(LP|ILP)"
$ 

The same is valid for support/config-fragments/autobuild/bootlin-riscv32-
glibc.config

$ riscv32-linux-gcc  -dM -E - < /dev/null | grep -E "(LP|ILP)"
$ 

I did not test other 32bit platforms because the only dependee of libvpl, 
intel-vpl-gpu-rt, is unsupported on 32bit archs anyway.

Regards, Bernd
