[Buildroot] [PATCH 17/22] dependencies: remove a few useless mandatory dependencies

[Thomas Petazzoni]

awk, bison, flex, makeinfo, gettext should be built as dependencies of
packages when needed. In practice, even the toolchain build doesn't
need any of these, and only a few packages do require them.

It is not needed to list gzip and bzip2 since they are already checked
through ${DL_TOOLS}: whenever a package needs gzip or bzip2 for its
extraction, the dependency is added.
