Looking at the binutils source, it seems to be the usual plugin type
code using dlopen, dlsym, etc in libdl, so I don't see this causing
any problems.

Looks like --enable-plugins now defaults to on in mainline binutils:

<https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=log;h=b879806f2fdd2eca7092d7b854d6cbbbbbd0493b>

We might need some tweaks to the native binutils so that it gets the
plugin location right, but the linker already depends on libdl, so
enabling plugin support shouldn't be a problem.
