Trac #33130: Fix silent "sage -b" after #32759

(from #33125)

#32759 slightly broke `sage -b`: It silently rebuilds sagelib and then
reports "Nothing to do".

This behavior comes from `build/make/install`, which first calls `make
-q sagelib` with output suppressed. But `-q` handling got broken by
#32759, as explained in #33125.

We fix it here.
