[Buildroot] Problem calling ldconfig in ext2root.mk

Hi Bernhard -

Thanks for taking a look at this problem.

Just tried it and unfortunately it didn't work.

$(if $(TARGET_LDCONFIG),$(TARGET_LDCONFIG) -r $(TARGET_DIR) 2>/dev/null)

I think the problem here is that the "if" is evaluating as
true because the string $(TARGET_LDCONFIG) is set. What it isn't 
checking is if the actual file exists.

Would a test like this work:

   @test -x $(TARGET_LDCONFIG) && \
     $(TARGET_LDCONFIG) -r $(TARGET_DIR) 2>/dev/null


or should TARGET_LDCONFIG be unset early on if it doesn't exist
(in which case your original patch would work fine)?
