The open-plc-utils source code has a condition for uClibc toolchains
when calling vfprintf(). But the non-uClibc case simply doesn't
build. And the recommended solution at
https://github.com/qca/open-plc-utils/issues/36 is to pass
-D__UCLIBC__ unconditionally.

# We unfortunately can't use TARGET_CONFIGURE_OPTS, as it would

+# Yes, we're passing __UCLIBC__ in EXTRA_CFLAGS, as it fixes a build
