configure: add -Wl,--no-as-needed
It is reported that combination of `--enable-shared --with-jemalloc`
breaks on Debian bullseye (testig). Deeper investigation revealed that
this system's `ld(1)` is patched, to turn `ld --as-needed` on by
default.
This linker flag strips "unnecessary" library dependencies from an
executable. In case of `ruby(1)` (of `--enable-shared`), because
everything is in `libruby.so`, the binary itself doesn't include any
calls to `malloc(3)` at all. So in spite of our explicit `-ljemalloc`
flag, it is ignored. Libc's one is chosen instead.
This is not what we want. Let's force our `ruby(1)` link what we want.
Fixes https://github.com/ruby/ruby/pull/4627
