Makefile: remove non-existent STAGING_DIR_TOOLCHAIN from dirclean

Openwrt's top level Makefile uses STAGING_DIR_TOOLCHAIN in the make dirclean
statement.
https://dev.openwrt.org/browser/trunk/Makefile#L55
    rm -rf $(STAGING_DIR) $(STAGING_DIR_HOST) $(STAGING_DIR_TOOLCHAIN)
$(TOOLCHAIN_DIR) $(BUILD_DIR_HOST) $(BUILD_DIR_TOOLCHAIN)

As far as I can determine, no such variable has been defined. I made a search
in Openwrt source repository and the one line in Makefile's dirclean command
is the only place where that variable exists.

The item has been introduced to Makefile by r8362, but even at that time
neither Makefile nor rules.mk defined such a variable. Most likely the goal
has been to set both staging_dir/toolchain and build_dir/toolchain to be
cleaned, but one of the variables has been erroneous. The correct variable
for build_dir/toolchain has been then added by r13494.

In current code,
    TOOLCHAIN_DIR = $(TOPDIR)/staging_dir/$(TOOLCHAIN_DIR_NAME)
    BUILD_DIR_TOOLCHAIN = $(TOPDIR)/build_dir/$(TOOLCHAIN_DIR_NAME)
so the item STAGING_DIR_TOOLCHAIN in the rm command is unnecessary.

Most of the time, we want to make sure OpenWrt has been configured and
setup before start running make. However, in case of package/symlinks,
forcing prereq as a dependency creates multiple issues:
*when executed on a clean workspace, it will prompt for user input
 and open a menuconfig window before executing the feeds command
*the only way around that is to provide a .config. However, the "prereq"
 target would then run a "make defconfig", which will remove all the
 packages in the .config but from external feeds, as feeds have not been
 installed yet.

The only way to currently work around this, is to generate a fake config
by running "make defconfig", then "make package/symlinks", copy the real
config (which at this point disregards the previously generated config),
and run make defconfig again. Something like this:

make defconfig
make package/symlinks
cp real.config .config
make defconfig

This change is removing the need for the first defconfig, making the
process more logical for OpenWrt users using the package/symlinks target.

This seems to cause issues on some build hosts, and it is not that
important.

When using GREP_OPTIONS to supply default options to grep, the buildsystem might get broken (For example adding --color=always breaks it)
This patch will empty the GREP_OPTIONS to prevent the described (and any other) problems related to GREP_OPTIONS
