[Buildroot] patch to allow selection of e2fsprogs tools to install

[Hamish Moffatt <hamish@cloud.net.au>]

Any objection to the following patch, which allows choice of which
e2fsprogs tools to install (a la package/mtd and others)?

I wish there were a better way to write the makefile other than a ton of
ifneq/endif lines. I suspect some sort of macro and $(call ..) could do
it.

I only omit tools at install time, not build time. This allows you to
build multiple projects with different tool selections if you wanted.
Plus, e2fsprogs does not support disabling most tools at build time.
