[PATCH 0/3] kcsan: Re-add GCC support, and compiler flags improvements

[Marco Elver]

Re-add GCC as a supported compiler and clean up compiler flags.

To use KCSAN with GCC before GCC 11 is released, the following will get
a stable GCC 10 and cherry-pick the patches required for KCSAN support:

        git clone git://gcc.gnu.org/git/gcc.git && cd gcc
        git checkout -b gcc-10-for-kcsan releases/gcc-10.1.0
        git cherry-pick \
            4089df8ef4a63126b0774c39b6638845244c20d2 \
            ab2789ec507a94f1a75a6534bca51c7b39037ce0 \
            06712fc68dc9843d9af7c7ac10047f49d305ad76
        ./configure --prefix <your-prefix> --enable-languages=c,c++
        make -j$(nproc) && make install
