Not necessarily, but it's software, so anything can be fixed, I just
don't want to force a toolchain update just yet on my users.

It works as a workaround for such toolchains, it's also just useful for
people who want to make use of it and speed up their search paths with
glibc-based systems.

What part are you asking about, re-thinking the 32-bit/64-bit library
paths or ldconfig in general?

It's fine not to accept these patches, I just don't see a reason why not
if it is useful to people like me (sorry for not fitting in the internal
toolchain model just yet), and possibly others as well. If you want this
hidden behind a CONFIG_USE_LDCONFIG, maybe that becomes more acceptable
in your eyes?
