But this means in uClibc and musl systems INTEGCK_DEBUG is still not
usable, right?
Instead of papering over the issue we should bite the bullet and add a
libmissing to mtd-utils
to same functionality across all kind of libcs.
IOW when mtd-utils is built against non-glibc we add -lmissing to the
compiler command line.
