Sorry, perhaps I didn't explain myself very well. My point was - can
we guarantee that uclibc has already been built by the time we are
builidng a package? If so the explicit dependency is not needed. Many
packages already do not depend on uclibc so I suspect that we can drop
any explicit dependency on uclibc.

An example:

# grep uclibc package/grep/grep.mk
# grep uclibc package/bash/bash.mk
bash: ncurses uclibc busybox $(TARGET_DIR)/$(BASH_TARGET_BINARY)
bash: ncurses uclibc $(TARGET_DIR)/$(BASH_TARGET_BINARY)

Why does bash depend on uclibc but grep doesn't? Does grep have a bug
or can we remove the unneeded dependency from bash?
