Using -fno-plt would be a nice tiny little performance boost at runtime but then it's important to make sure everything is compiled with -Wl,- z,now and there might be programs ignoring LDFLAGS but respecting CFLAGS. Ideally -z now would be the default in the linker first. If we aren't going to patch the default, then I think a configure flag for that needs to land upstream.
It's also worth noting that clang does not support the -fno-plt option and I couldn't find any discussions about adding support for it.
If it's only a tiny performance improvement, I strongly believe we should skip it for now.
