I looked again into my install-log:

libtool: finish:
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/sbin"
ldconfig -n /opt/xorg/lib

So, my first approach was to add...

export PATH="$PATH:/opt/llvm/bin"

...to my build_libdrm.sh script.
This did NOT help!

So, I enhanced the above PATH-line and added /opt/llvm/bin directory
where my clang binary is located.

$ sudo PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/sbin:/opt/llvm/bin"
make install

...which is successful!

Is there something like $LIBTOOLPATH or $LIBTOOL_PATH?

And why the hell do I have to do such manual workarounds?

Any help still appreciated!
