[lfs-support] glibc step: core1.o problem

Following the recipe in book v8.1, it fails on the step in
glibc (5.7) where it says to verify with compilation of a minimal c
program.

It claims it can't find the crt1.o object. This is however present in
the tools file tree, and the directory holding it shows up in the ld
search path. The "ld" command path itself seems a bit suspicious,
though.

The first time I went through this it worked without a problem. I messed
something up later on, tough, so I deleted all the contents in the /tools
directory and started over. I have now deleted and started over 3 times,
with and without deleting the unpacked source tars.

One thing to note is that I am installing in a loop-mounted fs that I
created using dd and mkfs.ext4. I don't know if that makes a difference?

Thanks for any advice on the matter.
