Gcc build fails with test_real_width is negative

[Mr Dini]

I am sure this is not a common practice, but since I couldn't get gcc to compile and I am out of ideas as to why libgcc is not picking up the environment variables, I decided to share the chroot I am trying to build from.

The file can be found here: https://mega.nz/file/qqBB2QKZ#mQVV3Vqyre6MYtdGJlx2rNq7el8Aiimr6uv4aTZR97g

When I chroot I firstly run the command to populate the environment variables:

. /opt/webos-sdk-x86_64/1.0.g/environment-setup-armv7a-neon-webos-linux-gnueabi

Then execute the following commands to start the build process:

cd /root/gcc-build

CC="arm-webos-linux-gnueabi-gcc -march=armv7-a -mfpu=neon -mfloat-abi=softfp --sysroot=/opt/webos-sdk-x86_64/1.0.g/sysroots/armv7a-neon-webos-linux-gnueabi" CXX="arm-webos-linux-gnueabi-g++ -march=armv7-a -mfpu=neon -mfloat-abi=softfp --sysroot=/opt/webos-sdk-x86_64/1.0.g/sysroots/armv7a-neon-webos-linux-gnueabi" ../gcc-6.2.0/configure --prefix=/opt/webos-sdk-x86_64/1.0.g/sysroots/armv7a-neon-webos-linux-gnueabi --with-mpfr=/opt/webos-sdk-x86_64/1.0.g/sysroots/armv7a-neon-webos-linux-gnueabi --host=armv7a-linux-gnueabi --target=armv7a-linux-gnueabi --build=x86_64-linux-gnu

make -j8

Right now, the folder contains a state where it fails with stdio.h no such file or directory. If you skip the configure part and run make -j8 directly after setting the env vars, you can see what's going on.

I appreciate any feedback!

Thanks
