New description:
libmpfr (and libmpfr and libmpc, #12515) are run-time dependencies of
`gcc` (#12369). These therefore become build-time dependencies of Sage.
When these libraries are deleted during installation of mpfr, gcc stops
working, causing build failures in parallel builds.
Since there is no clear reason why the old libraries should be deleted, we
simply don't delete them. The mpir `spkg-install` already doesn't delete
libraries and mpc will be fixed in #12515.
