# Linux rust build infrastructure does not currently support ccache
# see https://github.com/Rust-for-Linux/linux/issues/1224
# Quick summary: There are 2 issues: $HOSTCC is not escaped and rustc expect a path (and not a command)
# More details in: https://lists.openembedded.org/g/openembedded-core/message/229336
# Disable ccache for kernel build if kernel rust support is enabled to workaround this.
