Issue: sci-electronics/iverilog calls nm directly.
Discovered on: amd64 (internal ref: tinderbox)
As per QA policy, toolchain tools must not be called directly because they can cause issue in cross-compiling and because is not possible use a different NM implementation (like llvm-nm). To reproduce, please use sys-devel/gcc-config[-native-symlinks], sys-devel/binutils-config[-native-symlinks] and set the NM variable to x86_64-pc-linux-gnu-nm.
