[Buildroot] Avoiding rebuild of $(TARGET_DIR)/usr/bin/ldd

[Buildroot] Avoiding rebuild of $(TARGET_DIR)/usr/bin/ldd

[Ulf Samuelsson]

$(TARGET_DIR)/usr/bin/ldd gets regenerated each load.
When I study the output of "make -d", it gets rebuilt
because of 'gcc'.

I did the following to get rid of the rebuild, but I am not
sure it is correct.

Comments?

this was added to fix
sed -i -e "/JLEVEL/d" .config
echo "BR2_JLEVEL=1" >> .config
make -j 128

(i.e. toplevel parallel builds)

If your change works (i.e. if there is a rule somewhere to build
$(TARGET_CROSS)gcc, which i don't know off-hand) then please go ahead
and commit.
