Description Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2021-02-28 09:50:16 UTC 
I guess we should compile host tools and use the binpkg for the kernel itself only.


E.g.:
```
 * Preparing vhba module
make -j12 HOSTCC=x86_64-pc-linux-gnu-gcc-10.2.0 CROSS_COMPILE=x86_64-pc-linux-gnu- 'LDFLAGS=-m elf_x86_64' KDIR=/usr/src/linux modules 
make -C /usr/src/linux M=/tmp/portage/sys-fs/vhba-20200106-r1/work/vhba-module-20200106 modules
make[1]: Entering directory '/usr/src/linux-5.11.2'
  CC [M]  /tmp/portage/sys-fs/vhba-20200106-r1/work/vhba-module-20200106/vhba.o
cc1: error: incompatible gcc/plugin versions
cc1: error: fail to initialize plugin ./scripts/gcc-plugins/structleak_plugin.so
make[2]: *** [scripts/Makefile.build:279: /tmp/portage/sys-fs/vhba-20200106-r1/work/vhba-module-20200106/vhba.o] Error 1

    sys-kernel/gentoo-kernel-bin: Rebuild host tooling
    
    Rebuild host tooling from source when installing the binary kernel.
    This ensures that it is compatible with the system libraries
    and toolchain, in particular reducing the risk of gcc plugin version
    collision.
