This patch ensures that we don't record a reference to gcc-toolchain in
the result of `guix pull`.  With this, we save 150 MB of closure.

This is a patch to fix the first issue I found in
https://issues.guix.gnu.org/56030.

Subject: [PATCH] guix: self: Do not record reference to gcc-toolchain.

The ld-wrapper from gcc-toolchain records a reference to the library
path through rpath, but this is not needed.  By explicitely using rpath
flags instead, we save 150 MB of closure.

* guix/self.scm (quiet-guile): Do not record reference to gcc-toolchain.
