I’ve applied the patch.  \o/

I have one question for which I couldn’t find an answer in the previous
discussions:

> +           (lambda* (#:key inputs #:allow-other-keys)

> +                               "/bin/libtool")))
> +             #t))

The effect of this is to retain a reference to GCC, Libtool, and all
their dependencies, which makes the closure of FreeHDL much bigger.

We could avoid it by just putting this in ‘freehdl.pc’:

  cxx=g++
  libtool=libtool

Now, whether this will work depends on whether/how users of ‘freehdl.pc’
use these variables.

Could you check whether that would work?

TIA!

Ludo’.
