Issue: sys-block/mbuffer calls objdump directly.
Discovered on: amd64
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 OBJDUMP implementation (like llvm-objdump). To reproduce, please use sys-devel/gcc-config[-native-symlinks], sys-devel/binutils-config[-native-symlinks] and set the OBJDUMP variable to x86_64-pc-linux-gnu-objdump.
